I like him, but he is not in my top tier. The Senate is not really the place to audition for President. I would say he should run for Governor first, but Sarah is going to take that spot.
I will say one of my favorite things about him is that he is not a squish. He speaks very clearly and is direct. Not sure where he lands on the charisma chart, but I am a fan.
The name President Cotton alone will drive the Democrats ape.
