Just before the second debate between Hillary Clinton and Donald Trump was about to begin earlier this month, the Commission on Presidential Debates shut down Trump's alleged plan to seat a group of particular women in his family box. The women, all with no relation to any Trump, had accused former President Bill Clinton of sexual abuse. 。

Ahead of Wednesday night's third and final debate at the University of Nevada, Las Vegas the tactic of using strategic guests to throw off and distract the candidates seems to be alive and well -- despite efforts from the Commission to keep provocative guests out of the family seating areas.

he hasn't previously heard of candidates overtly inviting certain guests to the debate to psych out their opponent.。

It's a new tactic that Glasser doesn't think will succeed. "I don’t think it’s going to work on Hillary," he said. "She’s been under attack for decades and she’s withstood it."。

Because of this new strategy, Glaser predicts the Commission will be updating rules about debate guests in the future. "This election has broken all the norms, it’s utterly different from past elections," Glaser said.。

Interest in who the candidates are bringing to the showdowns has jumped dramatically. Previous election cycles in 2004, 2008 and 2012 saw small spikes surrounding debate guests. This year it seems everyone wants to know who will be used as a pawn to psych out the opponent.。
