Voters in the US will have one last chance on Wednesday (19 October) to see presidential nominees Hillary Clinton and Donald Trump battle it out onstage in a final bid to attract support before the 8 November election.

The Democratic nominee will look to continue her rise in the polls following two successful debates, while navigating the ongoing scandal regarding her emails as secretary of state. Meanwhile, Trump will have an opportunity to appeal to voters amid his growing sexual assault allegations.

The two political heavyweights have fought tooth and nail in the last couple weeks, with Trump attempting to cling to his summer lead in the polls. Several election polls released on Monday (17 October) show Clinton leading by as much as 12 points in a four-way race by Monmouth University with Trump and third party candidates Gary Johnson (Libertarian Party) and Jill Stein (Green Party).

Clinton leads by varying margins in polls by CBS News, Rasmussen Reports and George Washington University. The GOP nominee, however, only leads in one poll by the Los Angles Times/USC Tracking by a mere one point.

Neither Johnson nor Stein will participate in the final debate after failing to meet the required 15% support threshold.

Where and When

The third and final presidential debate will air live starting at 9pm EST (2am BST) from UNLV in Las Vegas, Nevada. The debate, which will be divided into six 15-minute segments like the first one, will be hosted by Fox News' Chris Wallace. The segments will focus on the following topics: debt and entitlements, immigration, economy, the Supreme Court, foreign hot spots, and fitness to be president.

Candidates will have two minutes to respond to questions and then additional time to respond to the other candidate's response.
