And, once again, I call horsecrap. Palin helped McCain to a lead in the polls, and then McCain utterly botched his handling of the financial crisis. He never recovered, so his handlers stabbed Palin in the back.
If Palin is such a lead balloon, then reconcile your claim with the fact that she has helped so many candidates win elections, and is a much-sought-after endorsement for so many pubbies.
