On this day in 1980 President Carter informed the U.S. Team that the United States was boycotting the Moscow Olympics in response to the Soviet Union's invasion of Afghanistan. On to today' top stories:

"Michigan Ends Revote Bid" (Jonathan Weisman, Washington Post) Saying that the state will turn to "other options," Mich. Gov. Jennifer Granholm conceded defeat in the revote effort. With Florida also failing to come to an agreement, the Clinton campaign finds itself in a bad situation.

"McCain Ahead in Some National Polls" (Christina Bellantoni and S.A. Miller, Washington Times) McCain's lead in a couple tracking polls means two things: 1.) the ongoing Democratic primary is benefiting McCain; and 2.) McCain now has a pretty good fundraising pitch to donors. Otherwise, it's still too early.

"Bill Richardson Endorses Obama" (Associated Press) Will it have any effect? It could with more moderate Democrats, who were part of Richardson's fanbase, and of course Hispanic voters.

"John McCain Praises British Forces' Sacrifice in Iraq and Afghanistan" (Richard Beeston and Tom Baldwin, Times of London) Although McCain had nice words for the British involvement in the war on teror, he raised some hackles by supporting the eradication of the poppy crop in Afghanistan through spraying. Apparently the Brits don't like spraying or they love poppies.

"McCain Raised $11 Million in February" (Mary Jacoby, Wall Street Journal) It's far behind the fundraising machines of Obama and Clinton, but for a month in which McCain battled conservative opposition to his candidacy, not bad. Still, Obama and Clinton are expected to report raising $55 million and $35 million, respectively.

"McCain Aide Suspended for Relaying Video" (Associated Press) For sending out a video linking Obama to pastor Jeremiah Wright, a McCain aide was suspended yesterday. The McCain camp said the aide's actions were against the campaign's pledge to run a clean campaign.

"Obama Campaign Says Clinton Misrepresented Her Support for Nafta" (Julie Bosman, New York Times) One of the findings in the newly released Clinton document is Hillary's involvement with NAFTA in the early 1990s. The Obama campaign wasted no time hitting Clinton for distorting her record.

"Obama Highlights War's Costs" (Mike Dorning, Chicago Tribune) Obama has spent his post-speech days talking the Iraq war and hitting both McCain and Clinton over their positions. Obama also previewed perhaps a general-election argument, tying the nation's economic woes to the war.

"Ranks of Democrats in State Surge" (Mike Cronin and Mike Wereschagin, Pittsburgh Tribune-Review) The ranks of Democrats in PA has risen by more than 100,000 since the fall, a testament to the excitement on the Democratic side, and, more importantly, both campaigns' efforts to bring Independents and Republicans on board. To do well in the state, Obama needs to swell the ranks of Democrats.
