To prepare for her first debate against Donald Trump, Hillary Clinton is taking an unpleasant walk down memory lane that includes stops at scandalous moments in her husband's presidency.

Trump has signaled that there will be no sacred cows in the presidential race, and the former first lady's campaign is bracing itself for the possibility that the billionaire will try to toss Clinton off her balance by bringing up Bill Clinton's affairs, Politico reports.

Monica Lewinsky and the infamous blue dress, actress Gennifer Flowers and Vince Foster, the longtime friend of Hillary who took his own life in 1993 while working at the White House, could come up during the Sept. 26 match at Hofstra University.

Then there's the drama of Hillary Clinton's own making - her decision to route her State Department emails through a private server she kept in her basement unbeknownst to other top officials in the Obama administration, including the president.

'You can't put it beyond Trump that Monica Lewinsky will play a role in this debate,' former White House counsel to Barack Obama Greg Craig told Politico.

Craig was tapped to play George W. Bush opposite John Kerry during the Democratic senator's 2004 bid. He also took on the role of John McCain for Obama in 2008.

He said of Clinton. 'She's got to be prepared to deal with the Foundation and Wall Street and super PACs and all of that. They need to be less focused on dealing with his policy proposals and more on dealing with the unexpected. He’s going to be in attack mode, probably the whole time.'

The Clintons have lived much of their lives in the public spotlight, generating a heap full of dirty laundry for Trump to re-air if he chooses.

He has already made reference to all three incidents at one point or another during the year and two months of his campaign.

Foster's death was ruled a suicide, but rumors persist he was murdered, most likely by the Clintons, as he was reportedly bullied by Hillary in the weeks preceding his suicide about the Whitewater land deal.

Trump in May said Foster's death was 'very fishy' and noted that he had an 'intimate' knowledge of the Whitewater investment.

'I don’t know enough to really discuss it,' Trump said of Foster's death. 'I will say there are people who continue to bring it up because they think it was absolutely a murder. I don’t do that because I don’t think it’s fair.'

A few weeks before that, as he girded himself for a wave of attacks from Clinton's campaign and her SuperPAC, Trump fired a warning flare and said that Hillary is 'an unbelievably nasty, mean enabler' of Bill's sexual affairs.

'She's been the total enabler. She would go after these women and destroy their lives,' Trump said at a rally. 'She was an unbelievably nasty, mean enabler, and what she did to a lot of those women is disgraceful.'

Bill Clinton admitted to affairs with Lewinsky, while he was president, and Flowers, once, in 1977, though she says it went on for years.

Hillary Clinton said in 2003 that she contemplated a divorce. The couple stayed together, though, and in October of 2015 they celebrated their 40th anniversary.

Clinton has succeeded in previous debates by staying on message, regardless of what else is happening around her. When Republican Rick Lazio left his podium during their 2000 Senate debate to shove a campaign finance pledge in her face, strategists point out that she did not become rattled

Clinton has succeeded in previous debates by staying on message, regardless of what else is happening around her.

When Republican Rick Lazio left his podium during their 2000 Senate debate to shove a campaign finance pledge in her face, strategists point out that she did not become rattled.

'She ignored him and didn’t take his bait,' retired Sen. Judd Gregg said. 'She got back on message.'

Gregg stood in for Al Gore on behalf of Bush's presidential campaign that year.

Neera Tanden, president of liberal think-tank Center for American Progressive, was part of Clinton's debate prep team in 2008, when Democratic contenders had 25 organized arguments.

'She gets nervous. But she gets mentally in the zone,'Tanden told Glamour last year as Clinton was getting ready to do battle in the 2016 primary. 'I never saw her right before a debate like super nervous.'

Tanden recalled the one time she believes Clinton gave a bad answer in those matches - when she was asked in October 2007 if she was in favor of driver's licenses for illegal immigrants.

Clinton said she did at the time, then said she didn't afterward. Now she does again.

'She doesn't get all freaked out, lose her crap, and everything. She doesn't sit there and go like, "Oh I'm never going to be able to do this again." '

Tanden said, 'She came back to the next debate and was good and on it.

'This is a woman who has kind of had to face stressful situations many times in her life, you know, this won't be the first stressful one she'll face and it won't be the last.'

Names that have been put forward as suggestions have ranged from former Saturday Night Live actors like Al Franken, now a U.S. senator representing Minnesota

Her campaign asked Howard Wolfson to play Obama in 2008.

According to Politico, Clinton's team is still searching for someone to imitate Trump.

Names that have been put forward as suggestions have ranged from former Saturday Night Live actors like Al Franken, now a U.S. senator representing Minnesota, to non-politicians such as billionaire investor Mark Cuban.

Cuban told the New York Daily News that he thinks 'it would be hard to truly play Trump because he is so removed from reality these days.' To Politico, he said he'd be 'happy' to do it if someone from the campaign asked him to, though.

Former Pennsylvania Governor Ed Rendell, who has put his foot in his mouth while talking about women on occasion, said to Politico, in jest, he's 'probably one of the only ones who says things bordering on the outrageous like Trump does.'

Another suggestion is that Clinton employ more than one Trump impersonator - one for each approach he could take. A politician of substance who's interested in talking about news of the day and the pressing national issues, or the attack dog he unleashes at his rallies whose goal would be to leave Clinton bleeding.

Trump could ignore Clinton altogether and try to win sympathy from the audience by assailing the debate's not-yet-named moderator as part of the dishonest media trying to undercut his campaign.

'The Clinton challenge is to prepare for the crazy Trump who will probably show up, some kind of toned down Trump, and the somewhere-in-between Trump,' Democratic strategist Bob Shrum, a member of Gore's debate team, told Politico.

Assessing Trump, Rendell said, 'He’ll say anything.'

'It’s almost impossible to be totally prepared.'

Trump has not formally committed to any of the three general debates, the first of which is scheduled for Sept. 26 just outside New York City.

He said last week that he 'absolutely' wants to spar with Clinton, though, and is looking forward to doing all three, once he sees and approves the conditions that have been set by the bi-partisan committee that handles the televised quarrels.
