Clinton, Edwards, Gingrich.
Although each case is different. It takes some megalomaniacal b@lls to run for president. It attracts a certain type of person. The type of person you may vote for but not the type you would want to date your daughter.
Edwards - Happened after he lost. Not legitimate.
Clinton - Happened during, so that's legitimate.
Gingrich - I haven't seen him accused of sexual harassment? I know he stepped down for ethics violations.
Newt didn't step down for ethics violations. He stepped down when the GOP lost a few seats in 1998 and some of the leadership convinced the GOP house that it was Newt's fault for why that happened.
The ethics violation against Newt was an absolute joke.
