The Twitter fit he threw afterwards made me realize that he is a petulant narcissist, just like Obama, only without the self control. He tried to backpeddle the negative flak it caused and I heard one interview he said he really meant her "nose" and another where he claimed he meant "eyes". It was clearly not what he meant.
I think he really was brought into the campaign to finish off the GOP brand once and for all with the intent to paint us as racist, sexist, and unprincipled bullies who cry to their attorney every time anything critical comes out about his past.
