Ann Romney Speaks Up on Twitter, Obama Has More to Say on 'Buffett Rule,' Plus More to Watch for Thursday in Politics

— -- There's likely to be more buzz Thursday about Democratic strategist and DNC adviser Hilary Rosen's accusation that Ann Romney has never worked.

"Guess what, his wife has actually never worked a day in her life," Rosen told CNN's Anderson Cooper on Wednesday evening during an interview about the "war on women."

Moments later, Ann Romney made her debut on Twitter: @AnnDRomney. Her first and only Tweet as of early Thursday morning: "I made a choice to stay home and raise five boys. Believe me, it was hard work."

One of Rosen's responding Tweets @hilaryr: "Please know, I admire you. But your husband shouldn't say you are his expert on women and the economy."

There was bipartisan disapproval of Rosen's remark about Romney, including tweeted disapproval from President Barack Obama's campaign manager Jim Messina and top Obama campaign strategist David Axelrod.

Elsewhere in politics Thursday, Obama will have more to say about the "Buffett Rule." The rule seeks to ensure that millionaires pay at least the same effective tax rate as middle class families. Obama will use interviews with TV anchors from Columbus, Ohio; Cedar Rapids, Iowa; St. Louis and Reno, Nev., to appeal to senators from those four states to support the rule when it comes to the Senate floor Monday. And while Obama is doing the interviews, Vice President Joe Biden will be in New Hampshire holding forth on the same topic.

Out on the GOP campaign trail, Newt Gingrich will be in Delaware, Ron Paul will be in Texas and Ohio Senator Rob Portman will be in Pennsylvania stumping for Mitt Romney.

And then there is this: Thursday marks the sixth anniversary of Romney signing health reform legislation in the Massachusetts that included an individual mandate to buy health insurance.

And this: Jury selection begins in the trial of former Democratic presidential candidate John Edwards. He was indicted last year on six felony counts for allegedly spending more than $925,000 to hide his mistress Rielle Hunter and their baby from the public at the height of his 2008 White House campaign.
