Obama's Coattails

As the president's popularity declines, so do the fortunes for other Democrat candidates.  From Public Policy Polling:

How big of a problem is Obama’s unpopularity for Democratic candidates? We’re finding that almost no one who disapproves of the President is planning to vote Democratic for key offices this year. And obviously if you’re in a state where the Obama disapprovers make the majority, that makes it virtually impossible for you to win if you can’t pick up some of those folks.

Maybe it's not an anti-incumbent OR anti-Democrat election. Maybe it's an anti-Obama election.

And if you're perceived to be with Obama (as a fellow Democrat), the voters may perceive you as being against America.
