I don't think this guy is some elite political operative -- and I can't really speak to why he didn't do that.
My guess -- he thought he was talking to a volunteer and didn't want to lose the help in a swing state. His actual thought process -- I have no idea.
he is not Karl Rove or Axlerod but he was heading part of his daddy's re-election effort. thats not chopped liver and anyone in a position of authority has no business condoning voter fraud. especially when his district is not in play.
