My own two cents on this question is that I want someone who's a FIGHTER and is going to blacken the eyes of the Democrats at every turn.
I love Newt and his experience and the fact that he's so well versed on every single issue but the fact is he hurts Trump. I don't see a Trump/Gingrich ticket winning.
I also don't see a Trump/Ernst ticket winning. Nor do I see a Trump/Christie, Trump/Sessions, Trump/Pence or about anyone else I can think of being a winning combination with Trump.
Don't get me wrong, I think Trump wins in the end, I just can't see who he wins with. There has to be a dark horse that Trump's keeping under wraps that's going to be the surprise announcement.
Personally I'd like a Trump/Thune ticket but I don't think there's an ice cube's chance in hell of that happening.
Problem with Ernst is we don’t know how she will react when she is punched in the nose by the Dems. Maybe literally. Trump needs someone he can trust who is experienced in the nuclear war of this campaign season.
