I have got a suspicion that Kathleen, who emerged on the conservative scene before Palin did, is quite miffed at the fact that she is no longer the media darling she started out to be. Therefore, she has to put down her rival.
Sarah is more true to real conservative beliefs. Kathleen Parker likes the spotlight.
She's definitely not a fan, that's for sure. And it goes back to when Palin was picked for VP.
