Republican National Convention 2012 Live Blog - Here's a lively and curated live blog of the events in Tampa surrounding the Republican National Convention . After Monday's delay due to Hurricane Isaac, the gathering of GOP delegates gets underway in earnest with a packed schedule that includes the roll call to officially select Mitt Romney as the Republican nominee and the whole thing ends tonight with New Jersey Gov. Chris Christie's keynote address. Inn between, Ann Romney, with a speech to the convention and interviews with the press, will seek to do more to humanize her husband. We got the first taste of that process with yesterday's interview of the 5 Romney sons by ABC's Diane Sawyer.

Make sure to watch ABC News and Yahoo! News' streaming coverage from 7 p.m. ET thru 11 p.m. ET at abcnews.go.com/politics/live

Call the Vote - Romney Officially Nominated - 5:05 p.m. ET - On the Republican convention floor, former Gov. John Sununu formally nominated Romney to be president. Now they'll call the vote. Alabama, Alaska, Arkansas… Missouri is expected to put him over the top.

Obama Tries to Rebrand 'Obamacare' as 'Romney-Doesn't-Care' - 4:37 p.m. ET - Jake Tapper reports on the president's counter-programming to the RNC:

President Obama coined a new nickname for a potential action by a hypothetical President Romney today, playing off the "Obamacare" nickname for health care legislation that his administration initially used, then rejected as pejorative, then re-claimed.

To a a crowd of roughly six thousand at Iowa State University in Ames, Iowa, the president today said, "It's up to you whether we go back to a health care system that let insurance companies decide who to cover and when. Governor Romney promised that sometime between taking the oath of office and going to the inaugural ball, he'd sit right down, grab a pen and kick seven million young people off their parents' plan by repealing health reform," the president said, referring to Romney's pledge in June to "act to repeal Obamacare" on his "first day if elected President of the United States."

Seat Them Now! - 4:28 p.m. ET - Signs of disunity when officials at the Republican National Convention declined to seat members of the Maine delegation, which was split between supporters of Ron Paul and Mitt Romney. The convention floor was divided between chants of "Seat them now!" and "USA."

Moments later, RNC Rules Committee Chairman John Sununu, a former New Hampshire Governor, and the Republican House Speaker, John Boehner, were met by cheers and boos as they announced and called a vote on a new set of rules. Read more about the controversy here.

Republicans Believe in Sher - 4:15 p.m. ET - Most people in the United States probably identify the singer Cher as the most popular woman with that first name. But soon, that could all change, ABC's John Parkinson reports.

Tonight, Republicans believe one of their star candidates, Sher Valenzuela, will burst into the national spotlight when she delivers a primetime address during the Republican National Convention.

Valenzuela, who is running for lieutenant governor of Delaware, is a small businesswoman who runs an industrial upholstery facility that manufactures everything from padding for Major League Baseball umpires to bulletproof vests for the Israeli military and protective covering for the U.S. military's Boeing's V-22 Osprey.

…

The convention's theme tonight, "We Built It," has also attracted some criticism toward Valenzuela, whose business employs about 70 people, because it accepted federal loans and contracts. Valenzuela said that when she launched her business from her garage, she applied for a Small Business Administration-backed loan.

"I had to put my house on the line for that loan and, thankfully, I didn't lose my house and, thankfully, I was able to create the jobs that I committed to provide," she said. "It's businesses versus big government. We don't need big government. We need a more efficient, lean government, and that's exactly the kind of government we intend to deliver."

"It doesn't matter if you have a D, or an I or an R after your name if you have a job - a J-O-B," she added. "It really matters to people that they have an opportunity to contribute to their economy in a very meaningful way, and this is outside party lines. So we believe that these are the solutions that America is craving."

Hit The Road Jack: Rep. Tim Scott, R-S.C., took the lyrics from "Hit the Road Jack" and sent a message to President Obama during his speech at the convention.

"Hit the Road Jack and don't you come back. No more, no more, no more," Scott said in a sing songy voice.

Scott dedicated this same song to Obama at a townhall last August while former Gov. Jon Hunstman, who was running for president at the time, played the piano. (Arlette Saenz)

Switcheroo - The RNC is looking to highlight some voters who backed Barack Obama in 2008 but now have switched to the GOP side with a new video that will air at the convention tonight.

Titled "Switchers," The video features testimonials from three voters expressing their support for Romney over the president, despite voting for Obama in 2008.

"I voted for Barack Obama in 2008. I'm definitely voting for Mitt Romney in 2012," one man says in the video.

And one high-profile "switcher" will be on display tonight. Rep. Artur Davis, who gave one of the seconding speeches to nominate Barack Obama at the Democratic convention in 2008 but has since turned to backing Romney, is set to speak just before the "Switchers" video airs. (Arlette Saenz)

Watch the RNC's Switchers:

The Convention Gavels to Order for Tuesday - 2 p.m.

Let the Lowering of Expectations Begin - Yahoo! News' Holly Bailey writes that Romney adviser Stuart Stevens sought to lower expectations for a post-convention bounce for the Romney campaign even as he argued that if the election were held today, Romney would win easily.

Speaking to reporters on board Romney's plane en route to Tampa, Stuart Stevens, a senior Romney adviser, said factors like Hurricane Isaac and the "back-to-back" scheduling of the RNC and Democratic National Convention could potentially depress any convention bump for the GOP ticket.

…

"We've never come into a convention where another campaign has spent a half a billion dollars plus the outside groups," Stevens said. "I just think all bets are off about any kind of past performance being a predictor of the future."

Stevens' comments come just weeks after a senior Romney adviser suggested Romney would see an 11-point bump out of the RNC. The adviser, who declined to be named, made the prediction just a day before Rep. Paul Ryan was named as Romney's vice-presidential running mate. The adviser told reporters Romney would see a bounce from both his VP and the convention.

Ron Paul's Minority Reporting for Duty - 1:58 p.m. ET - ABC's Rick Klein notes Rep. Ron Paul is roaming around the convention floor, prompting Paul supporters to chant "Ron Paul, Ron Paul" and "Let him speak," amid chants from Romney supporters in the crowd repeating, "Romney, Romney."

ABC's Aaron Katersky says Paul was wearing a red and white blue lei, waved to people in the stands, and signed autographs for supporters. Supporters also chanted "Seat them now," referencing the Paul's delegates who were struggling for recognition at the convention.

Here's a full rundown of Paul's march from Elizabeth Hartfield.

Barbour, Drink in Hand: Obama's a 'One Percenter', Romney 'Not as Conservative as I am' - 1:50 p.m. ET - Yahoo!'s Chris Moody noticed a great Youtube video of former Mississippi Gov. Haley Barbou:

"We've got two guys running for president, by the way, who are both very rich. Each one of them is in the top one percent in the United States." Barbour said during an event for the National Bloggers Club in Tampa. "Both of them are one percenters. And in fairness, both of them made their own money. Romney made his by winning the confidence of people who invested their money. …Obama made his money writing two books about himself. He's a one percenter!…Which one do you figure is going to do a better job of getting our economy going in the right direction?"

And -

"Mitt Romney's not as conservative as I am. It's a fact," Barbour said. "But the difference between him and Obama in terms of their vision, their plan, their policies, their belief in the history and the fundamental principles of America are the greatest difference of any two presidential candidates in my lifetime. …It behooves us to make sure Romney wins."

Palin Stirs the Pot Over Rules - Former VP candidate opposes controversial rule change, reports ABC's Chris Good from Tampa. Shecalled a compromise a "direct attack on grassroots activists." Good's report is here :

Some Republican National Committee members were up in arms Monday about a proposed rule that would weaken states' control of who gets to attend future national conventions as voting delegates. While primaries typically determine how many delegate votes candidates will receive, states typically meet later to fill out those delegate rosters. A new rule would allow presidential candidates to veto those choices.

Republican National Committeeman Jim Bopp, who had led the movement against the rule, reached a compromise with other RNC members Monday, but some of his fellow partisans have rejected it, according to internal emails obtained by ABC News.

Fanning the flames, Sarah Palin posted to her Facebook page urging Republican National Committee members to revolt against the proposed rule, which was supported by backers of presumptive GOP presidential nominee Mitt Romney.

Power Breakfast with Romney Power Players - ABC's Jonathan Karl and Yahoo!'s David Chalian sat down this morning for a live streamed panel discussion with Romney's top communications adviser Eric Fehrnstrom and the leader of his running mate search team Beth Meyers.

Breitbart to be Honored at RNC - He was a controversial figure and didn't see eye to eye with the Republican establishment, but the party will honor firebrand and media magnate Andrew Breitbart, according to Yahoo!'s Chris Moody .

The Republican National Convention will pay tribute to Andrew Breitbart, the late conservative activist and publisher who died in March due to heart failure.

Breitbart will be included in a moment of remembrance honoring Republicans who have died since the 2008 convention, the RNC announced Tuesday.

Bobby Jindal Not Happy With Obama's Disaster Relief - 1:10 p.m. ET - Here are two tweets from the Louisiana Gov, who is skipping the GOP convention to oversea reaction in his state to the hurricane.

1. @bobbyjindal: Yesterday the President granted a limited disaster declaration for the state that provides for direct federal assistance.
2. @bobbyjindal: However, the limited declaration does not provide for reimbursement of expenses that the state is taking to prepare for the storm.

Isaac Update - FEMA's Craig Fugate Respondse - 2:11 p.m. ET - From ABC's Matt Larotonda - During a conference call, Fugate briefly addressed Governor Jindal's concerns that the limited disaster declaration signed by President Obama would not reimburse the state for its own expenses regarding Isaac. The FEMA director says his agency is more concerned with the immediate storm danger and will address fiscal issues afterwards.

"That's a reimbursement program that will come after the fact, and we felt it was more important to get the first part of the request out, the ability to provide direct federal assistance, and then as the storm impacts we can assess that to determine the level of impact and assistance required," he said "The financial reimbursement piece would occur after the storm. We wanted to make sure we got the direct federal assistance made available to the governor so anything on the life safety aspect, we would be able to provide that assistance."

Obama's Isaac Message Won't Stop College Tour - 12:42 p.m. ET - Here's what President Obama said earlier about Isaac during a quick announcement in Washington before heading to a college tour that starts in Iowa.

"I want to encourage all residents of the Gulf Coast to listen to your local officials and follow their directions, including if they tell you to evacuate. We're dealing with a big storm and there could be significant flooding and other damage across a large area," he said.

As he finished, Obama ignored a question about whether it's appropriate to continue campaigning in light of the impending storm. Shortly after the statement he boarded Marine One on his way to a two-day, three-city campaign swing that will include stops in the critical election states of Iowa, Colorado and Virginia.

A Thursday Mystery - Who Warms up for Rubio? 11:22 a.m. ET - ABC's Arlette Saenz reports:

Top Romney advisors claim they have been left in the dark about a mystery speaker who may address the convention on Thursday night.

"I do not know. I'm intrigued," Eric Fehrnstrom, a senior advisor to Romney, told ABC News' Jonathan Karl and Yahoo! News David Chalian amid laughter at the ABC News/Yahoo! News breakfast in Tampa Monday morning. "I had not heard that that there was going to be a mystery speaker, no."

Other top members of Romney's team - senior advisor Beth Myers, director of advertising Ashley O'Connor, and pollster Neil Newhouse - also claimed ignorance about a surprise guest speaking Thursday evening.

The latest schedule released by the Republican National Convention Monday lists a "To Be Announced" speaker slated to speak just before Sen. Marco Rubio and the presumptive GOP nominee Mitt Romney. A number of Olympians, including Michael Eruzione, Derek Parra, and Kim Rhode, and senior advisor Bob White are expected to speak Thursday evening.

Christie's Advice for Romney - Open Up - 7:15 a.m. ET -The convention tonight will include keynote speaker New Jersey Gov. Chris Christie, who has become a force in the party after his election in 2009. He was an oft-mentioned potential running mate and an oft-mentioned future candidate for president.

The Guv talked this morning to George Stephanopoulos on GMA. Here's part of George's report on their conversation:

Christie had a tip for Mitt Romney when he takes the stage Thursday: open up to the American people.

"I've always said this George…Mitt Romney is going to have to win this campaign. And to do that over the next 70 days he's going to have to let the American people see who he is, put out a bold vision for the future. Remember, he's a challenger…Challengers always get a late look," he said.

Over the weekend Mitt Romney repeated the famous Popeye quote "I am who I am" in several interviews , implying that perhaps he wouldn't show more of his personal side this week.

Christie disagrees, and credits Rep. Paul Ryan for already bringing out a new side of the presidential candidate.

"I think you've seen [Romney] show a lot more of himself even since Paul Ryan has joined the ticket. I think Paul has brought energy to the ticket and he's brought great energy to Governor Romney after a long and arduous campaign. So I think that the American people are going to see a lot more of him and they're going to start seeing it tonight with Mrs. Romney," he said. "Who no one can speak better or more articulately about the man that Mitt Romney is and the leader he'd be for our country than Ann Romney so I think the fun starts tonight, George, and I think the American people are going to start to get a complete picture about who Mitt Romney is and why he'd be a great president."
