If the economy goes further down the drain than it already has, and Obama is massively unpopular due to that and other reasons, then I can see the map being like this
Is this map unrealistic? Probably, but nothing's impossible in American politics, and if Obama's unpopularity borders on Carter or Bush levels, than I can see something like this happening. I mean, who ever imagined in 2006 that the Democrats were going to win North Carolina and Indiana, of all states?
The country is way to polarized for something on that scale.
As of 2010, but who knows what's going to happen come 2012?
If the GOP was more Liberal on social issues, but they aren't going to do that within 2 years, especially with the huge conservative movement they have now.
No offense to you, but the GOP leadership has politically pissed away the Hispanic vote for the next decade or so. Therefore, the odds of Obama loosing California are virtually zero.
