Can You Smell What Clinton & Obama Are Cooking?

Pennsylvania Primary Polls Open: 7:00 am ET Polls Close: 8:00 pm ET Pledged Delegates at Stake in Primary: 158

It's only fitting that in the final hours before the polls open in Pennsylvania, after weeks of trying to position themselves as Friends of the Everyman Voter, Drinkers of Local Beers and Shots, and Bowlers of Strikes, both Hillary Clinton and Barack Obama will make one last pitch to Pennsylvania voters with appearances on Monday's broadcast of WWE's Raw.

Unfortunately they will not appear together in person as a late addition to the King of the Ring, eight-man single elimination tournament. But both candidates taped a message that will run on Monday's live show and in their messages they show they (or at least a 20-something staffer) are on top of the latest WWE dramatic plot lines (see: Randy Orton).

Not a bad way to reach over 3 million eyeballs, have a little fun and compare the long Democratic nomination race to a smackdown, dragged out professional wrestling match.

Obama:

"You know, this is a historic time for America. It's not just that the reign of Randy Orton may soon be coming to an end. It's that at this moment, in this election, we have a chance to finally end business-as-usual in Washington. For a long time now, we've had a politics where our leaders go after each other like they're competing to become King of the Ring instead of coming together to provide universal health care, fix our economy, and solve our other problems. That's what I'm running for President to change. So to the special interests who've been setting the agenda in Washington for too long – and to all the forces of division and distraction that have stopped us from making progress for the American people – I've got one question: Do you smell what Barack is cooking?"

Clinton:

"This election is starting to feel a lot like "King of the Ring." The only difference? The last man standing may just be a woman…

…I've been knocked down, but I've always gotten back up. And I know how to take a hit for the American people. And if things get a little tough, I may even have to deliver the "people's elbow." Because this country is worth fighting for.

Now, I promise to stick to the political arena. So don't worry Randy Orton you're safe... for now. When it comes to standing up for the American people though, I am ready to rumble."

Clinton better be in fighting mode because the stakes in Pennsylvania are huge for her campaign. She is up in every poll in the state but in some cases only by 5-6 points. While a W is still a W in college basketball and Major League Baseball, a win for Clinton needs to be convincing (8 points or more?) so she can:

-- Convince uncommitted superdelegates that she is the stronger candidates who can win key battleground states -- Continue to push the message that voters are having second doubts about Obama's electability -- Avoid the Wednesday post-mortem punditry that she barely escaped with a win in a state where she lead by double digits just weeks ago

-- Point out how she was greatly outspent by the Obama campaign, but money doesn't buy votes -- Justify staying in the race through the final nine contests despite the impossible delegate math she is facing

Things to look for on Tuesday:

-- Margin of victory.Ten points or more, the above arguments are a lot easier to make.

-- Turnout. There have been 151,660 newly registered Democrats since January 2008 and 163,727 voters have switched their registration to Democrat. This could be a good sign for Obama in a closed primary where only Democrats can vote.

-- Late deciders. ABC News' Polling Director Gary Langer reports that late deciders have recently been turning to Clinton. Keep an eye on late deciders because of the prolonged campaign period, massive amounts of cash spent on advertising and the sharp final arguments the two candidates are presenting in Pennsylvania. LINK

-- Philadelphia and the surrounding suburbs. The city is the state's largest, with a population of over 1.5 million, and is the most Democratic part of the state. The four surrounding suburbs (Montgomery, Delaware, Chester and Bucks) have been historically Republican areas but that has shifted for the first time in decades, with Democrats now outnumbering Republicans in Montgomery and Bucks county These four counties account for approximately 20 percent of all voters in the state

-- Voter breakdown by Congressional District (CD). Remember this is all about delegates and while 103 of the 158 pledged delegates at stake are awarded based on the outcome in each of the state's 19 CDs, not all districts are created equal, as ABC News' Teddy Davis reports.

-- Some districts are worth more than others, based on how heavy the Democratic vote was in that district in the 2004 presidential and 2006 gubernatorial general elections. So winning the more heavily weighted districts could allow Obama to make up ground in the over pledged delegate count even if he loses the statewide vote. Pennsylvania's 2nd congressional district (Rep. Chaka Fattah, an Obama supporter) has the most delegates up for grabs – 9 pledged delegates. The 12th District (Rep. John Murtha, a Clinton supporter) has 5 pledged delegates.

Clinton and Obama are all over radio and TV in an 11th hour pitch to voters. Clinton will turn up on MSNBC with Keith Olberman and CNN with Larry King on Monday night and network morning shows on Tuesday. Catch Obama on The Daily Show on Monday night, all three network morning shows on Tuesday morning and several Philadelphia radio stations on PA Primary Day.

The kicker:

"Why can't I just eat my waffle?"
