TRH
They are probably at least as solid on the 2nd and don't have the immigration red flags. I haven't read that much about any of the mentioned candidates. I'm not voting on them so my interest is minimal.
I doubt if any of them would be my first choice, but I'm not POTUS and I'm not making the decision. If I was deciding who to nominate I'd be doing a ton of reading and in person meetings if at all possible.
