If I were moderating a Republican debate I would ask ‘are you one of those kooks who believes the Earth is only 5,000 years old?’ That should knock about half the field out right there.
As an aside, there are more than a few in this thread lamenting their vote for Ross Perot. You actually didn’t throw your vote away as you probably would have otherwise voted for Bush1. If Bush1 had won the U.S. never would have gotten to experience the Clinton economic miracle. Sometimes throwing a vote away is a good thing.
