Is 'framing' part of the midterm elections battle?

Incumbent Members of Congress are most endangered, it seems, in areas not so bad off.

Maybe, as the story notes, many of the worst-hit areas are high-minority urban districts that aren't switching parties anyway.

Or, the election is in part about perceptions. Of course, if that's the case, I expect mainstream liberal pundits to trot out George Lakoff any minute now to talk about "framing."
