Whether it’s not a bad idea depends entirely on his plans for replacing the admittedly horribly corrupt system. Does he have a stated suggestion, or is he relying only upon riding to power on a wave of discontent and anger?
He has some economical ideas, however he poses as an Economy professor and not as a politician. I don't think he talks to the kind of people he should be talking to. He is angry and everybody is angry with the political situation, but that's not enough to really shift the majority of votes he needs to be elected.
I think he wants to run for the presidency. He won't win. But he will stir up the waters a little bit. However, I am afraid that once in the pit, he will be like anybody else, forming alliances with a side or the other. He has to.
