Trump opens door to contesting the election's results

Donald Trump kept floating the possibility today that he will challenge the results of the presidential election if there's a "questionable result," while teasingly promising to embrace the outcome "if I win."
The Republican presidential nominee said he would accept "a clear election result" but was reserving his right to "contest or file a legal challenge" if he loses.
It was his first attempt to explain his stunning warning a day earlier in the final debate that he might not accept the results.
Today, Trump brushed off the likelihood of that happening with a confident prediction that "we're not going to lose."

"I would like to promise and pledge to all of my voters and supporters and to all of the people of the United States that I will totally accept the results of this great and historic presidential election," Trump said. Then after letting that vow hang in the air, he added, "If I win."
Trump's musings about hypothetical Election Day scenarios came as his campaign was reeling from widespread astonishment over his refusal to commit to the time-honored American tradition of the election's loser acceding gracefully to the winner. Trump has warned repeatedly of impending, widespread voter fraud, despite no evidence to support him and plenty of evidence to the contrary.
