Unless you saw Frontline's two shows on the life of Bill Clinton then you probably have no idea who he really was or how hard he worked to make our lives better, better than we deserve. Our economy was better under Clinton than any president after him. You'll have to Google that information because they won't let me provide a link.
Yes, he was human, but he genuinely wanted to do good and we vilified him for it like we do all genuinely good people who don't keep a low profile (or we just kill them, like John Lennon, the Kennedys, Gandhi, Martin Luther King, Malcolm X, etcetera). Why is it that we don't seem to have a problem with the crooks in high places, is it because we identify more with dishonest people and compare poorly to the honest ones, or because we wish we had what they have no matter how ill-gotten it is?
This movie shows how hard it is for anybody to get into office whether they're good or not; how you have to play hardball if you really want to make it. Yes, it has some funny parts, as does life, but it's not really a comedy.
