What a bunch of shit. Perot didn't get a single electoral vote. He had zero chance of being president. At best he might have helped Clinton by skimming some votes from Bush.
Wallace is the next closest third party candidate that did anything of mention in the elections, he at least got some electoral votes, so is actually a better third party example. Should have been alive to vote for him.
All other third party candidates that got electoral votes in recent history were faithless electors. So, no, I reject your call to "preserve democracy" by pissing my ballot away and possibly helping a fascist dictator get back into the oval office. Thank you.
