I’m betting that Newt and Trump talked about different positions. Trump probably asked Newt what he would like. I’m betting Newt said VP was 2nd and he didn’t want to play the media games but nailing Congress...
I like the choice, because Pence will not upstage Trump. I think that was a risk with someone like Newt or Christie. They like to run their mouths, and with Trump, it would have been too much.
