This could be the state that shifts the election. Obama had been holding a 4-5% lead in Pennsylvania for awhile. Now, it is tied, according to this major electoral-state website: http://www.electoral-vote.com/evp2008/Pres/Graphs/pennsylvania.html And his lead in Minnesota is now down to 1% http://www.electoral-vote.com/evp2008/Pres/Graphs/minnesota.html And he is now behind in Florida by 7% http://www.electoral-vote.com/evp2008/Pres/Graphs/florida.html
The one problem with the polls, as I understand them, is that they rely upon "likely" voters, and to determine who is a likely voter they use past voting trends and whatnot. That means that they are probably massively discounting the African American and youth votes that Obama has energized and probably will vote en mass for the first time in history.

It is called the Bradley effect: http://en.wikipedia.org/wiki/Bradley_effect Even if 1% difference in the election, it may be a major surprise in some states. West Virginia was a shining example when Hilary strongly outpolled Obama...
