I'm not assuming anything. I'm not sure. I think some would follow Bush and Rubio and some wouldn't. It would be a mess. But I'm sure there are some who dont want him on that stage and now is the moment to strike.
BTW, where the F is Rand Paul. As far as I can tell he still hasn't denounced Trump's comments on Mexicans and rape. Havent heard anything about this. He was late with a comment on SCOTUS SSM (and that ended up with his weird 'lets stop marriage entirely thing'). I'm not sure he has said anything yet on the IRan deal either. Is he still running for POTUS?
Rand Paul isn't exactly good on racial issues. He met with Cliven Bundy, who thinks blacks were better off as slaves.
