Unshackled Trump and confident Clinton to clash in final presidential debate

Donald Trump is unshackled; Hillary Clinton looks unstoppable.

The stage is set for Wednesday's presidential debate asTrump gets perhaps his last major shot at widening his base and Clinton looks to score a rare clean sweep in all three of their showdowns.

Fox News anchorChris Wallace will moderate the duel at the University of Nevada in Las Vegas. Itpits a newly liberated Trump, who tweeted last week about being freed fromthe"shackles"of theRepublican establishment after partyleaders deserted him, against a confident Clinton, who continues to lead in national polls despite a steady drip of WikiLeaks disclosures seized upon by politicalenemies as evidence of collusion.

Clinton, meanwhile, "has a heck of a lead to blow," said Geoff Skelley, an analyst with the University of Virginia's Centerfor Politics.

She's ahead ofTrump in all national polls and has a 6.9-point lead, according to the RealClearPolitics average.

With that in mind, Skelley expects Trump to take a "scorched-earth" approach in the debate.

The New York real-estate magnate will likely continue to diverge from the Republican Party's top brass by blasting America's democratic process as a sham electioneered by "global elites."

"He's already inclined to do something maybe that reeks of desperation," Skelley said, recalling the town hall debate when Trump tried to get prominent seats in the audience forwomen who accused Clinton's husband, former president Bill Clinton, of sexual abuse.

This time around, Trump will bring the president's Kenyan-born half-brother Malik Obama as his guest.Malikreportedlytold the New York Post that he's "excited to be at the debate," and said:"Trump can make America great again."

At tonight's debate, "he's going to try to flummox her and try to get her off her game," Skelley said. Though that's probably not a wise strategy.

This should be the time to temper some of his bluster and show voters a more presidential persona, said Arizona Republican strategist Sean Noble.

"If he comes in prepared, this could make for some impact on the race," Noble said. "But if 'unshackled' means he's not going to be prepared like I've seen, then this debate is going to be very bad for him."

Clinton needs to keep cool

All Clinton needs to do at this point, Noble said, is keep her cool, play a cautious game and avoid unforced errors.

Trump, on the other hand,"needs to have a strong grasp of the facts and stay disciplined."

"But I don't expect he'll do what I suggest," Noble said.

Debate coaches expect "emails" will be a popular word in Trump's attacks. But not justabout Clinton'sadmitted misuse ofclassifiedmaterialson her private emailserver while she was secretary of state.

The whistleblowing organizationWikiLeakshas been publishing daily batches ofemailsstolen by suspected Russian hackers from the personal Gmail account of Clinton'scampaign chairman John Podesta. Included are excerpts from Clinton's paid speeches to Wall Street, as well as an address to a Brazilian bank in 2013 that included a line referring to her "dream" of "open trade and open borders."

"Trump's got WikiLeaks on his side, so 'emails' will definitely come up," said debate analyst Todd Graham,director of debate at Southern Illinois University at Carbondale.

In an increasingly ugly election cycle darkened by Trump's insistence the outcome will be "rigged" in favour of Clinton, the faintest whiff of collusion from her camp could turn toxic fast.

Brazile,a CNN panel contributor at the time,denies leaking any question.

But if authenticated, Graham said, the emailwould showan outrageous breach by Brazile. Grahamimagines how Trump might use that for ammunition during thedebate.

"He might say to [Clinton], 'That's a good answer, did you get that from DonnaBrazile?'" Graham said.

Adding to her troubles are new FBIdocumentsreleased by the bureau this week, which allegethe State Department offereda "quid pro quo" deal to declassify anemailon Clinton's private server. The FBI and State Department have officiallydenied any such offer was made.

High stakes

This being the last debate the one that will be freshest in voters' minds as they head to polls next month the stakes are high. Scientific polls awarded decisive wins to Clinton in the first two debates. A third win would be a feat that Graham says "almost never happens," and would forceuncommitted Republicans to continue searchingfor a reason to vote for Trump.

"A lot of people will be hoping the debates give them their reason. Three [losses] in a row would be a big deal."

Unlike in the first debate, in which the candidates stood at podiums, or the town hall forum that allowed the candidates to roam the floor, Round 3 is expected to take place atashared table.

Mitchell McKinney, a former consultant for the Commission on Presidential Debates, wonders whether the side-by-side arrangement might soften hostilities between the candidates.

A table debate is typically less heated because the candidates are closer to one another, he said.

"They're having a conversation, if you will. And I think that could work against Donald Trump if his strategy is to be boisterous and attack-oriented," McKinney said. "It might appear like, 'Wow, that looks inappropriate.'"

Just let Trump talk

Fox News anchor Chris Wallace debuts on Wednesday night as the channel's first moderator for a generalelection presidential debate. Though the network tilts conservative, pundits and journalists generally agree Wallace is even-handed and will ask tough questions of both candidates.

Trump shouldn't necessarily expect to have a friendly face at the table.

Graham, the debate coach, has advice for Clinton as well, though it may sound counterintuitive: Don't worry about talk time. A good strategy might be to let Trump speak more and expose his vulnerabilities when it comes to policy specifics.

"Her answers are too darn long. She keeps talking over the moderator, and she just needs to shorten her answers," Graham said. "She can stop with extra time left and say, 'That's my position, my outlook. I'd like to ask Donald Trump what's his again?' Then see what happens."

Wednesday's final presidential debate begins at 9 p.m. ET and will last for 90 minutes without ad breaks.
