Oh it's certainly that obvious. I just find it amusing that you think Carson is a legitimate candidate as well. I suppose you're one of those Trump/Carson people.
Actually, what I said was that Carson’s integrity was better than the others’ lack of it.
Beyond that, I do think that demographics are a good reason to pick a VP candidate.
I would be looking for a capable person first, and then for one that could sway a state not already in my column or sway a demographic group that would help me or hurt my opponent.
Carson is better on that scale than Cruz who is from Texas. Texas will go republican no matter what. Hispanics might see Ted as one of them. I’m not sure on that one.
Rubio would sway Florida and he’d have Hispanic support.
Bush is actually dislike in Florida and he’d sway white anglo saxon amnesty pimps, I suppose.
Kasich would sway Ohio and he also is a wasp.
Carson has both Michigan and Maryland as home states, so that would put new territory into play. He also is black, and that will sway some of those blacks in his direction.
So, analyzing just those six, Rubio, Carson, and Kasich come off best as VP picks.
