TPM:

The DCCC now plans to spend $1 million against Rep. Michele Bachmann (R-MN) in the wake of her McCarthyite rant on Hardball, sensing that voters back home might end up turning against her extremism. A TV ad should be coming in the next few days. Meanwhile, the Cook Political Report has changed its rating on Bachmann, downgrading her by two whole positions from "Likely Republican" to "Tossup."

I can’t think of something more horrifying for a candidate than having a bad TV moment that instantly pumps $1.74 million into the coffers of your opponent.  

Would send a very nice message to the eliminationist crowd about the new limits of the bs you can spew on TV.
