I think he did well. I am still wary of Rand (probably because he's overly cautious so it comes off as dishonest at times) so I am still very careful about him but he did well. This interview is a plus in my book.
He is definitely different than his father in a sense that he's not as blunt and straight talking (one of the reasons we all like Ron Paul) and I'll just have to get used to that. But I can definitely see that there is still the same underlying philosophy there and that's a big plus.
I'll still be following his speeches and interviews until I can make the final decision about him, but this one definitely increased my respect for the man.
