VIEWERS' GUIDE: Candidates hone final arguments for Round 3

WASHINGTON (AP) — It was barely three weeks ago that Donald Trump opened the first presidential debate by asking, with faux deference, if it was OK to refer to his opponent as "Secretary Clinton."

By Round 2 he was back to calling Hillary Clinton "the devil."

[...] the Republican candidate's scorched-earth campaign tactics have left all sides wondering just how low things will go in the third and final presidential debate, coming up Wednesday night.

Trump in recent days has tried to deflect attention from the allegations about sexual advances by complaining that the election process is rigged against him.

Without providing any evidence, he wraps together the potential for voter fraud with assertions that his female accusers are part of a plot to smear him.

With millions of viewers tuning in, will Trump dwell on conspiracy theories or give voters a more positive reason to vote for him?

The emails include excerpts of Clinton's closed-door speeches to Wall Street interests and lots of campaign strategizing over how to contain the political damage related to her handling of classified emails and her use of a private email server.

The campaign took a dramatic detour last week when a series of women came forward with allegations that Trump made sexual advances toward them.

With a number of Republican officials in open revolt against Trump and worried that he will be a drag on the rest of the ticket, watch to see whether Trump gins up more discord with his party — and whether Clinton steps in to make the case for Democratic control of the House and Senate.

Trump tried to throw off Clinton by seating three women who have accused her husband of sexual impropriety in the front row of the audience at the second debate.
