I believe Rand Paul is the best pick. He has the constitutional street cred of Ted Cruz without much of the baggage. He’s establishment enough to have Mitch McConnell owe him a huge favor, yet he’s still considered by many to be non-establishment. He’s anti-amnesty, pro-gun, pro-life, and well spoken. He isn’t perfect, but his pluses outweigh his minuses.
I can’t think of a better pick, honestly. The only issue is that he’s in a race for his senate seat. It depends on what that looks like. If it’s a slam-dunk, then it’s all good. Otherwise, that could be a problem.
I like Rand Paul, too. He’d suit me to a tee...well spoken.
