Greta Van Susteren spoke to Bob Cusack and Betsy Woodruff tonight about how GOP presidential candidates will deal with Donald Trump at tomorrow's Fox News Republican presidential debate.

Cusack pointed out that as the front-runner, Trump will dominate the headlines and media coverage, so the other candidates are basically obligated to go after him.

Greta said that can be a dangerous game, since Trump is known to fire back at his critics.

"If these guys want to get in the news, they're going to have to somehow be connected to Trump," Woodruff said, adding that she believes every news story written about the debate will include the Trump's name.

"These guys have to go head-to-head with him, just if they want to get any sort of attention at all," Woodruff said.

Cusack agreed that the other candidates will try to punch Trump's buttons, but he believes that Trump will actually be measured in his responses.

He said one wildcard is Jeb Bush, and it will be interesting to see if the former Florida governor decides to take any shots at Trump.
