Trump won't accept election results if he loses as Clinton expands campaign into red states

With less than 3 weeks left until Election Day, the bitter contest between Hillary Clinton and Donald Trump escalated again into sharp, personal attacks during the final presidential debate of 2016. The Republican nominee said he may not accept the results of November's election and reserves the right to file a legal challenge. Clinton is leading in battleground state polls and is expanding her campaign into traditionally Republican states, but the former secretary of state is facing her own troubles with the continuing slow-drip Wikileaks release of hacked campaign emails and allegations this week of quid pro quo between the State Department and FBI. Plus, down-ballot Republicans have distanced themselves from some of Trump's most recent comments. As Election 2016 enters the final sprint, we get an update on the state of the race.
