Well, since we're comparing presidents to notorious persons of the past then I'll compare Clinton to Charles Manson.... and those who defend him to Manson's followers
1. Manson's followers have elevated him to a godlike status, even giving him powers that he does not have. (Clinton supporters have done almost the same thing, crediting Clinton for the 1990s economy, claimining he was tough on terrorism)
2. Manson's followers will defend everything that Charles Manson does, no matter how heinous (Clinton supporters will defend him for committing perjury, lying to the American public, Whitewater and a host of other wrongs)
3. Manson's followers blame society in general for his fate (i.e. the fact that he's in prison) and ignore the fact that they are really the consequences of his actions (Clinton supporters like to blame conservatives and that gosh darn "right wing conspiracy").
P.S. Wouldn't it be a gas if in a few years a rock band named "Marilyn Clinton" came along? The lead singer could dress up as an ex-president and the rest of the band members can dress up like interns!
