Trump handled the question well.
Rand Paul just got b*tch-slapped by Trump.
Actually, I think it was a big blunder for Trump.
I would have said something along the lines of, “I refuse to give the Republican establishment a blank check.I certainly hope to support the eventual nominee, but just like a hundred million voters out there, I will demand that they earn my support.”
Instead, what he said seemed to have a subtext: “Vote for me, or I just might throw the election to Hillary.”
