You could be right about Gibson, he's quite conservative. He could be just depressed and has had enough.
I THINK I figured it out...I think he is doing this because he is angry, depressed...and his job forces him to have to sit by and interview LIBS that are gloating all of the time...
THEREFORE, not only is he acting out that frustration...but he is trying to get his audience so mad...they will vote just to prove him wrong...LOL
