A defiant Donald Trump used the high-profile setting of the final presidential debate here Wednesday night to amplify one of the most explosive charges of his candidacy: that if he loses the election, he might consider the results illegitimate because the process is rigged. Questioned directly as to whether he would accept the outcome should Democratic nominee Hillary Clinton prevail on Nov. 8, Trump demurred. “I will keep you in suspense,” the Republican nominee said. Clinton called Trump’s answer “horrifying,” saying he was “talking down our democracy.” Trump responded angrily to a question about the chorus of women who have stepped forward in recent days to accuse him of unwanted kissing and groping, in some cases recalling episodes dating back decades. “I didn’t know any of these women,” Trump insisted, dismissing all of their stories as “lies.”
