Today's update includes a new poll which moves Nevada from "Leaning Obama" to "Leaning McCain". The state is of course still in the "Leaning" category which means it is really too close to call. But now McCain has the slight edge.
McCain Best Case - McCain 313, Obama 225
Obama Best Case - Obama 336, McCain 202
And if everybody gets their leans (and Obama gets DC) - Obama 272, McCain 266
Do you see how close that is? Wow. Close. Actually, if everybody got their leans, but DC (where we still have no polls) went for McCain, we'd have a 269-269 electoral college tie. Which would be awesome.
Of course, the odds of McCain winning DC are probably about the same as me spontaneously quantum tunneling to the moon. So I don't think we have to worry about that. :-)
