I had to look it up again myself. I knew it was higher than 11% off the top of my head, but was thinking something more like 14-15%. I had forgotten it was that high, and he was polling at 30% nationally the summer before the election. He briefly was leading in some polls in California and Texas. I don't think he would have won if he didn't do that weird drop out, but it would have been far more interesting.
The thing about Perot is that although I agreed with some of his politics, and if I could vote in 1992 I probably would have voted for him, I'm not sure exactly how good of a President he would have been. Being a good President is about more than just having good policy. He was a strange guy, control freak, who didn't work well with others. That's one thing to be that way in the business world (especially at a company you started) but quite another to be that way when President. Our current President falls into that category too.
