On this day in 1973 the Supreme Court issued its Roe v. Wade ruling. On to today's top stories:

"Voices Are Raised in Democratic Debate" (Dan Balz and Shailagh Murray, Washington Post) Yowza! Most of this primary season's debates have had one or two really combative moments, but last night's Democratic debate in South Carolina offered viewers several between Hillary Clinton and Barack Obama. Oh, right, and John Edwards was on stage too.

"Clinton Plan: Let Bill Lash Out" (Ben Smith, The Politico) At least some of the animosity on stage last night stemmed from Bill Clinton's attacks on Obama, which the candidate said were "factually inaccurate." But as reporter Smith notes, Bill's attacks, once thought to be hurting his wife's campaign, haven't actually cost her any primaries, and might be helping her.

"A Scramble Across Florida as Republicans Square Off" (Elisabeth Bumiller, New York Times) With most polls showing John McCain taking the lead over Rudy Giuliani, the two campaigned across Florida, appealing to the state's large Hispanic population. Best line so far: "I'm afraid that I may have to send my 95-year-old mother over to wash Chuck's mouth out with soap," said McCain, referring to Huckabee supporter Chuck Norris' comment that McCain was too old to be president.

"Romney Tops Polls in Key Florida Vote" (Joseph Curl, Washington Times) Surprisingly, however, a Rasmussen poll shows Mitt Romney with a 5-point lead over McCain, even though McCain still holds the lead in the RCP Average.

"Huckabee Trims Costs, Press Travel" (Charles Babington, Associated Press) Without a primary victory since the Jan. 3 Iowa caucuses, Mike Huckabee is adapting to a depleted war chest by campaigning in Florida on a shoestring budget.

"Same as She Never Was: Clinton Is Running Now as the Underdog" (Amy Chozick, Wall Street Journal) Beginning with her New Hampshire victory, Clinton has benefited from her "comeback kid" status. But, after a few more victories, that distinction will be harder and harder to defend.

"Delegate Tallies Depend on Who's Counting" (Josh Gerstein, New York Sun) A bit confused over this whole delegate thing? You're not alone. Having gone for so many decades where delegate-counting didn't much matter, campaigns, journalists and the public are confronted with making sense of the confusing state-by-state process. (RCP keeps track of the delegate count here.)

"Rudy Giuliani Trails John McCain Among Likely GOP Primary Voters in N.Y. - Poll" (Celeste Katz, New York Daily News) A new poll out shows McCain flanking Rudy on his home turf with a lead in New York. Many of the Feb. 5 states, like New York, will likely watch to see how Florida goes, but it's not a good sign for Rudy.

"Clinton Limits Time in SC" (Beth Fouhy, Associated Press) Although far from conceding South Carolina to Obama, Clinton is hedging her electoral bets by limiting her time there while shoring her support in the most important Feb. 5 states.
