A 25 Percent Chance

Nate Silver isn't panicking yet:

Of the 86 elections that we made calls on the morning of November 4th, 2008, only 6 (the Senate election in Minnesota, and the Presidential elections in Florida, Indiana, Missouri, North Carolina and North Dakota) featured contests in which the trailing candidate had a 25 percent or better chance of prevailing. The outcome of this election remains more uncertain than that of at least 90 percent of other elections, even if it's less uncertain than it was 24 hours ago.
