Trump stated that his first concern would be if the person would make a good president and secondly that he/she could help with congress. My guess is Gingrich who I think would probably be a pretty good choice.
That’s who I think it should be. Newt Gingrich would be a good choice if he wants someone who knows the inner workings of Congress and for crafting policy. He would bring more conservative street-cred to the ticket. The down side is it’s two older white guys.
