David Frum points out a big problem Rand Paul is going to have if he seeks the presidency next time out. He's going to have to denounce a lot of his father's supporters and maybe even some of what the Old Man himself says.
Actually, I think it's way too early to be talking about presidential contenders now. I have a hunch that the Republican nominee, and maybe even the runners-up, aren't even on anyone's radar at the moment. Same with the Democratic nominee if Hillary doesn't run.
