All this “oooh, but Palin endorsed Perry” is making a mountain out of a mole hill. Yes, back in 2009 she endorsed the GOP candidate Perry for his re-election as governor of conservative Texas. Big whoop. Who the heck do you think she was going to endorse, RAT KBH???
She could have stayed out of it and endorsed nobody at all if it is true that Perry is “as RINO as they come”, as was stated. That would mean that Perry was no more conservative than KBH, therefore no endorsement at all would have been a choice. She was under no obligation to be involved as far as I know.
