A &##x22;debate&##x22; between former Presidents Bill Clinton and George W. bush has been nixed because the promoter overhyped it as a death-match faceoff between the men, The Post has learned. Clinton spokesman Matt McKenna said the appearance was never slated to be a &##x22;debate&##x22; and was actually a moderated panel discussion with the 42nd and 43rd leaders of the free world. &##x22;This event ... was supposed to be a discussion between the two former presidents, and has been cancelled because it was not being billed as such by an overeager promoter,&##x22; McKenna said.
