So, when can Palin challenge him in a primary?
Will not happen because she campaigned for him.
Maybe even Cruz will have to campaign in AZ. for an alternative.
This should also be a warning for The establishment. You run McCain and he loses, then turn around and run Romney for an embarrassing loss with 8% unemployment. Being middle of the road mush is not what attracts voters to your cause. We need bold conservatives to win back the presidency and the Senate.
