Romney, Santorum, Gingrich, Paul All Campaigning, While Obama Heads to Florida, Plus More to Watch for Tuesday in Politics

— -- The headlines say Mitt Romney has the GOP presidential nomination wrapped up, and the delegate count overwhelmingly adds up in Romney's favor. But you wouldn't know it from Tuesday's campaign schedule.

Romney, apparently taking nothing for granted, will be campaigning ahead of the April 24 primaries in Delaware and Pennsylvania, which is Rick Santorum's home state.

Santorum, whose 3-year-old daughter Bella got home from the hospital Monday, has at least two events planned in Pennsylvania for Tuesday afternoon.

Newt Gingrich, who conceded on "Fox News Sunday" that Romney is the likely nominee, will be campaigning in North Carolina, while his wife, Callista, will be stumping for him in New York.

And even Ron Paul will be out on the campaign trail. He has a town hall planned at Texas A&M University.

If the fat lady has sung, not everybody heard her.

President Barack Obama heads to Florida Atlantic University in Boca Raton to speak about the economy and the "Buffett Rule" on tax fairness. There's a good chance he'll continue campaign manager Jim Messina's Monday attack on Romney. Messina accused Romney of "hypocrisy" for saying the president is a member of a coddled, out-of-touch, Harvard-educated elite.

And then there is this: If you missed first lady Michelle Obama last week on "The Biggest Loser," relax, grab the remote and settle down on the couch. She's on again tonight at 8.
