At the time there were many people who cursed Perot for splitting the two party vote, however he did get 18.9% and that is pretty incredible considering how entrenched attitudes were at the time for voting Democrat to make sure the Republican didn't win and vice-versa.
I have watched Perot's political adverts from the era and I thought he was a breath of fresh air. If I was American and of voting age at the time I like to think I would have voted for him and not succumbed to the peer pressure to vote Democrat.
Even the idea of a third party candidate was ahead of its time. Ralph Nader must have been informed by the success of Perot.
