Clinton, Trump set for last debate as ugly race nears finish
The hacking of her top campaign adviser's emails revealed a candidate that is averse to apologizing, 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, Wednesday's contest in Las Vegas comes just under three weeks from Election Day and with early voting already underway in several key battleground states.
Trump has leaned on an increasingly brazen strategy in the campaign's closing weeks, including peddling charges that the election will be rigged, despite no evidence of widespread voter fraud in U.S. presidential contests.
Republicans desperately hope Trump can close the campaign by focusing on 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.
The businessman has shown flashes of renewed focus in recent days, including highlighting a senior State Department official's request that the FBI help reduce the classification of an email from Clinton's private server.
Moderator Chris Wallace — the first Fox News journalist to moderate a debate — has said he plans to ask the candidates about debt and entitlements, immigration, the economy, the Supreme Court, foreign hot spots and their fitness to be president.
