He was correct to hate George H. W. Bush Sr.'s policies. Look what the NWO, WTO, FTAs, repeal of Glass–Steagall instead of reforming it, etc... etc... etc... have wrought!
Sure, Perot had some problems with his own economic platform and many more with his social platform. I especially didn't like his desire to implement more federal involvement in small business and authoritarian federal government tendencies. And, like you said, he had a reputation for instability in his personal life. But 80% of his economic platform was correct.
Bush Sr, on the other hand, was nothing BUT trouble all the way down the line. We'd have ended up in a better place if Perot had been president instead of Bush.
If we could have had the best of Perot's economics minus Bush and gotten Buchanan to implement them (which he would have as Buchanan agreed with Perot on those items), we'd have come out shining.
Heck, even Ron Paul may have done a better job than Bush Sr did. He ran in 1992 also, as did Buchanan, against George H. W. Bush Sr. for president.
Perot spent a lot of money on running for president just because he hated Bush.
