But by all means vote your conscience, if it makes you feel better and elects an Obamabeast.
The only thing you can possibly blame Perot for is that, by and large, he criticized Bush more than Clinton, and his presence largely took the spotlight off Clinton's sexual scandals that MAY (I emphasize may) have gotten some press attention. But that's doubtful.
But if right now I could trade Bush (whom I love) and a Dem House/Senate/statehouses/governors for Clinton and the 1994-1995 GOP House and the energy and idealism of that period, I'd do it in a minute. Aside from the WoT (big aside, I know), we got more accomplished as a majority in the House, even without the Senate, than we did by owning all three branches of government.
