From MSNBC's First Read team (emphasis added):
Obama at 264: A week after Obama's poll numbers spiked in battleground states and after McCain's campaign announced it was retreating from Michigan, Obama has opened up a nearly 100-point electoral-vote lead, according to NBC's new map. Obama now has a 264-174 advantage over McCain, up from his 212-174 edge last week. The changes are all in Obama's direction: We've moved Michigan, New Hampshire, Pennsylvania, and Wisconsin from Toss-up to Lean Obama. Also, every single Toss-up state is now a red state, and we are close to moving another red state -- Missouri -- to the Toss-up column. But let's remember: This is where the RACE IS RIGHT NOW, not where we expect the race to be in a month. And we move a state into lean when we believe there's significant evidence based on our reporting and a few of the public polls (we trust) that a candidate has a lead of five points or more.
So, this is all very tentative and subject to change at a moment's notice (just ask John McCain) but a month out from election day, this looks good.
