Here are the current predictions out there from the serious prognosticators - remember, 270 electoral college votes are needed to win:
|Princeton Election Consortium||303||235|
All of them have Obama significantly above the 271 mark. Several states that have been polling consistently for Obama would have to change to Romney for him to win. Realistically both Ohio and Virginia would have suddenly vote Romney contrary to what all the polling is saying.
It is now more likely that Obama will retain all the states he won in 2008 than lose either of Obio of Virginia.
Meanwhile in the House of Representatives it looks like the Democrats will take a number of Republican seats, anywhere from 6 to 20 seats when compared with the 2010 results. The best estimates I can find have the results as 208 to 227.
In the Senate it looks like the Democrats will win 52 or 53 seats to the Republicans 47 or 48.
