US presidential debate: Can Donald catch the last straw to prevent a 'trump' from Clinton?

Democrat Hillary Clinton and rival Donald Trump wade into their last presidential debate Thursday with the Republican candidate spiraling downward in the polls amid allegations of sexual misconduct and wild charges of a "rigged" US election.

With less than three weeks to go before Americans cast ballots on 8 November, polls showed Clinton widening her lead over the Republican nominee.

The 90-minute debate at the University of Las Vegas, Nevada offers Trump what may be his last chance to turn around a campaign that has been battered by a stream of allegations he groped and forced himself on women.

His supporters remain intensely loyal, but there are few signs he's attracting the new backers he desperately needs.

"We've only just begun to fight, believe me," Trump said while campaigning in Grand Junction, Colorado Tuesday. "This is our final shot, folks."

Clinton has kept a low profile in recent days, shutting herself in with aides at a hotel near her home in Chappaqua, New York to prepare for the third televised debate of the campaign.

She takes the stage facing challenges of her own. 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.

Both candidates on Tuesday jetted separately into this gambling and entertainment capital in the Nevada desert ahead of the high-stakes encounter.

The last in a trio of presidential debates, Thursday's contest in Vegas comes just under three weeks from Election Day and with early voting already underway in several key battleground states.

Moderated by Fox News journalist Chris Wallace, the event begins at 0100 GMT (6.30 am IST), before a televised audience expected to number in the millions.

The candidates will be asked about the debt and entitlements, immigration, the economy, the Supreme Court, foreign flashpoints and their fitness to be president.

The past two debates quickly degenerated into highly personal, mudslinging attacks that pushed substantive policy issues to the side.

Clinton "should do what she did in the two first debates which was largely remain calm, deflect criticism and attacks and let Donald Trump continue to self-destruct", said John Hudak, a senior fellow at the Brookings Institution.

"If your opponent's ship is sinking you don't throw them a life preserver," he said.

Debate lessons

Trump undoubtedly will draw on the lessons of the past two debates, and sharpen his attacks on Hillary over Syria and Libya.

The jihadist attack on the US diplomatic mission in Benghazi, Libya on 11 September 2012 remains a burning issue among Republicans, who hold the former secretary of state partially responsible for the deaths of four Americans, including the ambassador.

Trump has invited Patricia Smith, the mother of a communications expert killed in the attack, to attend the debate, according to Yahoo News. During the last debate, he invited four women, three of whom had accused former president Bill Clinton of sexual assault.

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.

An average of recent national polls shows Clinton with about 46 percent support to 39 percent for Trump and 6.4 percent for Liberatarian candidate Gary Johnson.

Trump predicts an electoral surprise, or "new Brexit", on 8 November.

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 Clinton for being a creature of Washington who won't be able to bring about change.

But as Trump's lost ground, the New York billionaire has attacked the election process itself, complaining of a massive conspiracy to rig the elections against him.

"The press has created a rigged system and poisoned the minds of the voters," he said Tuesday.

"Either we win this election or we lose the country."

'Stop whining'

In a stinging rebuke, President Barack Obama on Tuesday told Trump to "stop whining" and go try to make his case to voters.

"I have never seen in my lifetime or in modern political history any presidential candidate trying to discredit the elections and the election process before votes have even taken place. It's unprecedented," Obama said, appearing with Italian Prime Minister Matteo Renzi in the White House Rose Garden.

"If, whenever things are going badly for you and you lose, you start blaming somebody else, then you don't have what it takes to be in this job," he added.

The White House is increasingly concerned that Trump and his supporters will not recognize the election's outcome, plunging the country into a political crisis.

According to a poll by Politico and Morning Consult, 41 percent of American voters, including 73 percent of Republicans, now believe the vote could actually be stolen from Trump.

But Clinton's campaign believes Trump's hot rhetoric has helped Democrats — not only by galvanizing supporters but also shifting undecided voters to their camp.

"We know that he thought that strategy of scorched earth would depress our vote, but if anything, we have found that it's helped to motivate our voters," Clinton communication's director Jennifer Palmieri said.

Democrats are beginning to target traditionally Republican states in a bid to run up the score and help win legislative races that could decide who controls Congress.

On Thursday, First Lady Michelle Obama will campaign in Arizona, which has not voted Democratic since Bill Clinton's landslide win against Bob Dole in 1996.

You can catch the live coverage of the final debate on at 6.30 am IST on Thursday.
