GOP Presidential Debate: 5 Things to Watch Out For

11 are slated to be on stage. Each candidate has their work cut out for them.

It seems likely that Ronald Reagan’s rule -– never speak badly of a fellow Republican –- will be violated several times in his own presidential library.

Each candidate has their work cut out for them. Here are the five things to watch for when the top Republican contenders face off.

1. TRUMP WAGES A WAR ON 10 FRONTS

2. FIORINA STEPS INTO THE SPOTLIGHT

After a hard fought battle off the “kids’ table” for a chance to play in the big leagues, Fiorina has officially earned a spot on the GOP primetime debate stage. Fiorina, who shined at Fox’s “Happy Hour” debate last month, comes ready to make some noise, especially towards Trump. Even though Fiorina is an outsider, she’s yet to seize on the support that Trump and Carson have seen, remaining stalled in the single digits in the polls. Expect the only woman in the packed GOP field to go after the mogul for his statements about women. Trump recently attacked Fiorina’s appearance in a Rolling Stone magazine interview saying, “Look at that face! Would anyone vote for that? Can you imagine that, the face of our next president?!” These comments are sure to become central to her attacks on The Donald.

3. CARSON REACHES THE MOMENT OF TRUTH

5. CAN BUSH CLAW HIS WAY BACK INTO THE RACE?

The second debate presents an opportunity for Bush, a chance to recover from an uninspiring performance during the last debate. But can he seize it? He's sinking in the polls, having rapidly lost his frontrunner status to political outsiders Trump and Carson. He’s also been criticized for being "low-energy", opting to answer questions in his typical cerebral, wonkish style, rather than the more theatrical effect to which many credit Trump's rise in support. After many vigorous on-the-road sessions, Bush says he's ready to tout his "conservative" record as former Florida governor. Advisers also say he'll campaign hard, though we shouldn't expect him to throw the first punch. As Bush told a crowd in Salem, New Hampshire last week, "I’ll campaign hard, if someone comes at me — bam! — I’ll come back at them."
