Perot, and an uncontested MSM that was in love with the Clintons and set out to paint President Bush as out-of-touch, aloof, a patrician who didn't give a damn about the American people, and, most outrageous, as a wimp. A certified war hero but he was a wimp compared to the dope-smoking draft-dodging horny hick from Hope. As for what Perot's personal animus was with George Bush, I dont know.
I think it was about the Vietnam POWs. He hated McCain for the same reason.
