Will Clinton use final debate to counter Trump's 'rigged' claims?

Hillary Clinton faces off against perhaps the most unpredictable version of Donald Trump for the third and final debate Wednesday night in Las Vegas, amid her opponent’s increasingly loud cries of an election that is “rigged” against him as he falls in the polls. Last week, Trump tweeted that he was glad the “shackles” had finally been taken off him, and then repeatedly told his supporters that “large scale voter fraud” and other alleged — but unspecified — malfeasance means the U.S. election is “rigged” against him. Trump also has pushed back on new allegations from several women that he groped them in the past, and suggested at a rally that one of the women was not attractive enough to assault.
