Palin can actually help some in the Carly vs Campbell battle, but nothing could be done to make Devore suddenly make up a consistent 20 point deficit to knock out Campbell, but Carly has the money and position to close a 4 to 7 point gap with Palin's help, especially if Devore drops out in a week or two.
So, I see you go by who can win, regardless if they are the right person for the job - Conservative or not. If that is your idea of winning, you will be at the end of the line when the Socialists give out their gifts.
You are trying to win without regard to who you are voting for - a common problem today.
