I have a history of exposing politicians, particularly when it comes to their private lives. A juicy sex scandal used to result in a politician being disgraced out of office. His or her political career would be dead. It was a good way to clear out the trash every once in a while.
But times have changed. Now scandalized politicians either stick it out and stay in office (like David Vitter or Larry Craig) or they resign, wait a couple of news cycles and successfully run for office again (like Mark Sanford). The question is, why do voters vote these scumbags back into office?
