The always excellent, even though leftist, election analyst at Electoral-Vote. com
has the map below up today. He bases his state by state review on day to day polling and has a very good record-I believe he only missed out in his final predictions in 2004.
What this map shows is that on current polling President Obama doesn't need Florida/Ohio/North Carolina/Iowa from the battleground states. He could win even with the loss of Colorado's 9 Electoral College votes.
As I have posted on a number of occasions Virginia is the key state for Obama. If he wins it he has a straightforward path to EC victory, without it he may be in trouble, but current polling looks good for him there.
There is of course a lot of water to flow under the bridge before November especially with the world in such economic instability but on current polling Obama looks like an easy winner.
