Bush Card?

I am somewhat skeptical of the Democratic strategy of using George W. Bush as a punching bag this fall but when you look at who the undecided voters on the generic ballot for the national poll we'll release later this week it starts to become more clear why it could be an effective strategy:

-They disapprove of Obama by a 38/48 margin and their approval numbers for Congressional Democrats are 16/64. So they're not very happy with how things are going.

-At the same time 51% of them think the current state of the economy is still George W. Bush's responsibility to only 27% who think it's Obama's, and 55% of them would rather have Obama as President to only 28% who are feeling Bush nostalgia.

These folks aren't happy with how things are going. But they were even unhappier with how things were going a couple years ago. Playing the Bush card may just convince them it's better to stay the current course, even if they don't love it, than to go back to the old one.
