On May 9, President Donald Trump said that “Ross Perot cost (President Bush) the 1992 election.” See here.
Nothing is more certain than the fact that Perot did not cause President Bush to lose the election. Perot dropped out of the 1992 race on July 17 and didn’t re-enter until October 1, 1992. During that time opinion polls showed Bill Clinton leading Bush. Furthermore, the exit polls asked Perot voters who they would have voted for if Perot had not been running, and the results were a tie between Perot voters who said “Bush” and Perot voters who said “Clinton.”
