How can the nine other Republican candidates at tomorrow’s debate take on Donald Trump?

Debate coach and Northeastern University professor Alan Schroeder offered suggestions for debating the GOP front-runner at tomorrow’s Fox News-Facebook Debate, which will kick off at 8:50p ET.

1. Ignore him.

Schroeder said he likens Trump to a hungry crocodile. "He's there, he's hungry, he's looking for something to snap on," Schroeder said. "If you stay out of his way, maybe he won't snap at you."

Still, Schroeder acknowledged that this tactic could prove difficult for Wisconsin Gov. Scott Walker and former Florida Gov. Jeb Bush, who will be next to Trump on either side and are therefore "right in his line of fire."

2. Denounce him.

Schroeder said that lower-ranked candidates who need to generate headlines for themselves could take on some of Trump's more controversial statements and use that to differentiate themselves.

3. Challenge him.

Schroeder advised candidates to “challenge him on his record, not on his rhetoric,” remarking that some of Trump’s positions through the years are not in line with the Republican Party.

Tomorrow's debate is an opportunity for Trump to look less like a celebrity and more like a plausible president, Schroeder said on this morning's "Fox and Friends." He added that Trump's inclusion in the debate will likely draw a nontraditional audience to the event, given Trump's celebrity status.

The following 10 candidates qualified for tomorrow's prime-time debate: Donald Trump, former Florida Gov. Jeb Bush, Wisconsin Gov. Scott Walker, former Arkansas Gov. Mike Huckabee, retired neurosurgeon Ben Carson, Texas Sen. Ted Cruz, Florida Sen. Marco Rubio, Kentucky Sen. Rand Paul, New Jersey Gov. Chris Christie and Ohio Gov. John Kasich. Tune in tomorrow for complete debate coverage, starting at 5p ET on Fox News Channel,, and the Fox News Mobile apps.
