Analysis - Anthony Zurcher, BBC News, Las Vegas
So which Donald Trump is going to show up at the final US presidential debate?
Will it be the Republican nominee who has offered reform-oriented policy proposals like term-limits for members of Congress and more stringent regulation of government lobbyists? Or will it be the candidate who has predicted "large-scale voter fraud" on election day and continued to launch nasty personal attacks on his Democratic opponent?
Over the past week Mr Trump has offered hints of a campaign that could have been - one that capitalised on fatigue from eight years of Democratic rule and presented a can-do message of outsider-oriented change.
Instead, Mr Trump has spent the bulk of his campaign offering Americans dark warnings of rampant crime and economic ruin, punctuated by off-message rants that exacerbate the impact of personal scandals and gaffes.
Given Mr Trump's performance in the first two debates - and the fact his campaign has invited a motley assortment of debate guests, including a woman accusing Bill Clinton of sexual assault and President Barack Obama's estranged half-brother - chances are we'll see more of this blunderbuss approach.
That strategy hasn't worked for Mr Trump so far, however, and now time is running very short.
