It's a scare tactic. That is precisely why it is used and precisely why it is being used now. Perot could have won in 92 easily had he not left the race and wiped out his broad support. That is part of the lesson of 92. The other part is not for voters; but, for the GOP. Clinton is what you get when you betray your base and then scare your third party candidate out of the race.. which I actually think was the doings of both the traditional parties as a means of keeping control between them. Whether I'm right or not.. that's for history. Perot could have won. A Perot today would find himself in the same position - capable of winning. The question is, who will it be.. not if.. who.
Did you vote for Perot?
The lesson of '92: Beware of third party candidates who are put up not to win, even if it means they have to exit the race for a while because they are getting to much support.
