Maybe I am wrong, but I don't believe Perot ran in the primaries, he just came out of nowhere and declared, so it's really not the same thing.
But there is a Perot like candidate, that is going to take votes away from whomever the Republican nominee is, in the works that will be on all 50 states ballots, plus the territories. That could hand the presidency back to the current occupant.
Perot was an Independent. It’s not the same as Gingrich. Newt is relying on the brokered convention. If Newt or more likely Ron Paul runs as an independent after dropping out of the race, then you’ll have another Perot. Incidentally, I voted for Perot since he was the only one talking about the debt. Well here we are and still no one is listening. Anyway, just make Newt the next President. I really don’t know why this is a hard decision. He will destroy Obama in the debates and will rise in the polls head-to-head with Obama as the public realizes what a fraud and joke Obama is as he is truly exposed by Gingrich.
