Has been said better by the immaculate Jay Smooth:
I will add that for a guy who presents himself as "principled," Paul put on a virtual clinic of sophomoric logical fallacies. I could probably teach a class session on dirty arguments just with his responses to Maddow: ad hominem! straw man! cheap appeals to sentiment! (Meanwhile, Maddow was doing what I would tell every student to do: stick to established facts and ask questions about them. She's no cheap shot artist; she stuck to Paul's own public statements.)
Rand Paul was impressive, but not in the good way.
