Just get that, and you've got the whole point. And if you think a TV show can't beat a regular old politician, well, you just don't know, or don't acknowledge, what most Americans spend most of their time doing. If you condemn the Clintons for their smarminess, their trashiness, their egotism, their bad character, their villainy, their egotism, you're simply reinforcing their TV show's value. Indictments just feed their ratings. I think he could have indicted either Bill or Hillary before the 1996 Presidential election.
TV shows fail when their character's cool runs out.
TV shows fail when their leading characters start to look ridiculous. TV shows fail because a competing show fields an even cooler character, and the volatile audience starts to watch somebody different. That's about it. Thus the George W. Bush juggernaut. As a competing character, he's showing signs of being able to out-cool Clinton.
