LOL! I hardly think so.
Hardly think what, that they'll think about impeaching, or that they'll succeed? I'm not saying they will succeed in impeaching Jeb Bush. In fact, they wouldn't even expect to succeed in forcing him from office. It takes 2/3 of the Florida House and Senate to do that, and that'll never happen, however much the democrats, the media, and lots of people here on FR want it to.
What they could hope for, probably reasonably, is to cause him so much political damage that he would be effectively neutered for the remainder of his term, and that some of that damage would spill over to his big brother George.
