Various Predictions of the US Presidential Race and other races

I thought I would go through the list of a bunch of the sites that are making predictions on how the electoral college count will go in the US Presidential Race and how the  pundits think the house and senate will go as well.

Presidential Race - the variation amazes me:
Site               Obama  Romney Toss-up
Huffington Post     332    191    15
electoral-vote.com  328    206     4
Nate Silver         309.3  228.7
Washington Post     255    206    77
AP Projection       247    206    85
Real Clear Politics 247    191   100
NY Times            237    191   110
CNN                 196    159   183
USA Today           196    191   151
What I find interesting that at the Huff Post the race is done but at US Today Romney and Obama are almost tied.
