In a recent episode (117) of This Week in Tech, there's a funny exchange between mainstream goody-goody host Leo Laporte, who at first says he can't understand why online purchases should not be taxed like other sales. John Dvorak berates him and, as Leo admits in episode 119, finally changed Leo's mind. Laporte asks Dvorak if he likes Ron Paul; Dvorak says yes, but he's not going to vote for him. Shortly later, after thinking about it, Dvorak changes his mind. This occurs at about 17:00 to 21:15.
Also of note, in the 10/25/07 Slate Gabfest podcast (27:25 to 29:00) John Dickerson talks about the possibility of Ron Paul "surprising" people in New Hampshire.
