On this day in 1991 the first Gulf War begins. Also on this day, in 1919, Prohibition takes effect. On to today's top stories:

"Romney Victory Scrambles GOP Field" (Jonathan Martin, The Politico) Mitt Romney's decisive victory last night in Michigan might put to rest ideas that the former Massachusetts governor was nearing the end of his run. What it doesn't do is give the GOP field any clear frontrunner heading into South Carolina, whose primary has traditionally decided the nominee. With five viable candidates still in the race, there are five roads to the nomination.

"Romney Did Well In Most GOP Demographic Categories" (Mark Hornbeck, Detroit News) A thorough breakdown of exit polling data: Romney did well among Republican and conservative voters, while John McCain captured what independent, Democratic and moderate voter there was -- which wasn't enough. On the Democratic side, though Hillary Clinton walked away with the uncontested win, 7 out of 10 black voters voted "uncommitted."

"McCain Vows He'll Win in South Carolina" (Tom Raum, Associated Press) After New Hampshire, the goal for McCain was to roll the victory into Michigan, and then be in the strongest position to take South Carolina. It didn't happen, but McCain is promising victory anyway.

"Democratic Presidential Rivals Discuss Race in Debate" (Christopher Cooper and June Kronholz, Wall Street Journal) In a debate that came on the heels of a racially-tinged controversy between Clinton and Barack Obama, the overall tone on the candidates last night was conciliatory. With each candidate praising the other's commitment to racial equality, it seems that both wanted to put the controversy to rest, or at least appear to want that. Otherwise, the debate focused on issues relating to Nevada, like the Yucca Mountain nuclear waste site (all opposed) and appealing to the Hispanic vote.

"Charges of Dirty Campaign Tricks Fly in South Carolina" (Jim Morrill, McClatchy Newspapers) It's beginning to look a lot like 2000. One group calling itself Vietnam Veterans Against McCain charges that the former POW pilot collaborated with his North Vietnamese captors, while a McCain flier charges that Mitt Romney provided taxpayer-funded abortions. Not surprisingly, the charges are denied by both sides.

"9 Jewish Leaders Say E-Mail Spread Lies About Obama" (James Barron, New York Times) The "Obama is a Muslim" emails are back in the news, with Jewish leaders concerned that they are now being deliberately spread among Jews. The leaders released a statement condemning the emails, but have not endorsed any candidate.

"Obama Camp Suggests Clinton Will Break No-Florida Pledge" (Sam Youngman, The Hill) An Obama spokesman yesterday said there were hints that Hillary Clinton might campaign in Florida despite all the Democratic candidates pledging not to do so. Because Florida will have no delegates, winning there means little, unless one candidate tries to claim otherwise.

"Hearing Is Set on Lawsuit Over Sites for Casino Workers" (Paul Kane, Washington Post) Just days before Nevada's primary, a federal judge has set a hearing for tomorrow to determine the legitimacy of the use of Las Vegas casinos as Democratic caucus sites. Supporters of Clinton filed the complaint, angering the Culinary Workers Union, which has endorsed Obama.

"Two Backers Start Drive to Draft Bloomberg" (Associated Press) It's the story that won't go away, but considering it would seriously impact the 2008 race, you might as well keep up with it.
