Of course he's going to take that step. He can hurt them in a lot more ways than they think he can. Seems like people would have learned not to fuck with this guy by now... he's a smart cookie, you fuck with him and he's going to make you pay for it. He's demonstrated that time and time again through the primaries and general election.
