Of course you answered your own question. :) Hasselbeck has good intentions, but she’s easily overpowered by the other three obnoxious liberals. They don’t ever dare even the playing field at two a piece, or put a real strong-spoken conservative like Ann Coulter or Laura Ingraham on there. They don’t because they know how they’d end up - battered and bloody every single day.
On the other hand:
She IS conservative, she IS smart, and she IS on the show.
I'll take that as a plus and leave Laura, Ann, and Michelle to carry on with their work.
