He definitely needs a woman on the ticket. I was hoping for Michelle Bachmann or maybe even Marsha Blackburn. Sadly Sarah Palin would probably be a drag on the ticket.
AFAIK, only Sarah Palin is in that select group. She's been out of office 8 years, and carries sufficient baggage of her own. Not sure that's what Trump needs.
He is wise to hold off on the VP pick until the convention. He needs the drama of the selection to bring in ratings and viewers. It must be unique and exciting. The goal should be to offer up an exciting convention that will draw in watchers—musical groups, right wing Hollywood people, Party stalwards and such—Bush and Mittens not coming might be a good thing. Who wants to hear them?
