Hillary Clinton and Donald Trump's ugly and acrimonious battle for the White House is barrelling toward the end, with the candidates taking the debate stage today for one final primetime showdown.
For Mr Trump, the debate is perhaps his last opportunity to turn around a race that appears to be slipping away from him.
1 NEWS NOW will live stream the presidential debate from 2pm today.
His predatory comments about women and a flood of sexual assault accusations have deepened his unpopularity with women and limited his pathways to victory.
His supporters remain intensely loyal, but there are few signs he's attracting the new backers he desperately needs.
Mrs Clinton takes the stage facing challenges of her own.
While the electoral map currently leans in her favour, the Democrat is facing a new round of questions about her authenticity and trustworthiness, concerns that have trailed her throughout the campaign.
The hacking of her top campaign adviser's emails revealed a candidate that is averse to apologising, can strike a different tone in private than in public, and makes some decisions only after painstaking political deliberations.
The last in a trio of presidential debates, today's contest in Las Vegas comes just under three weeks from Election Day and with early voting already underway in more than 30 states.
Republicans desperately hope Mr Trump can close the campaign by focusing on Mrs Clinton's weaknesses, a strategy some privately concede may not be enough at this point for him to win, but could help GOP Senate candidates salvage their races.
Mrs Clinton, who has meticulously prepared for the three debates at the expense of time in battleground states, visibly rattled Trump in their first showdown by using his own controversial comments about women and minorities against him.
The businessman was on the defense at the start of the second debate — which came days after the release of a video in which he brags about kissing and grabbing women — but ended on stronger footing, hammering Mrs Clinton for being a creature of Washington who won't be able to bring about change.
Mr Trump denied in the second debate that he had made the kind of unwanted sexual advances he is heard describing on the video.
His denial prompted some of the women who have since publicly accused him of assault to come forward.
