Don't miss the Fox News-Facebook Republican debate, Thursday August 6, live from Cleveland, Ohio at 8:50p ET, moderated by Megyn Kelly, Bret Baier and Chris Wallace.

The average of major national polls shows Donald Trump with a significant lead heading into Thursday's Fox News-Facebook Republican debate. 

According to the Real Clear Politics average (shown above) Trump is over 20% support, well clear of Scott Walker and Jeb Bush. The battle right now is for the final few spots on the stage at the primetime debate. 

Bill Hemmer spoke to two of the candidates who are right on the top 10 cut line: New Jersey Gov. Chris Christie and former Texas Gov. Rick Perry. 

Christie said he's confident he will be on the primetime stage, calling it an "important first step" to make the cut. 

"I'll be there on Thursday night," said Christie. 

Perry said he's focused on the "long game," highlighting the importance of early voting states Iowa, New Hampshire and South Carolina.

Hemmer asked whether being on the primetime stage matters to Perry. 

"I won't say it doesn't matter. But in the long haul, it doesn't make that big of a difference," said Perry, adding that the campaign will be won or lost in the early states, not in a debate. 

Perry then questioned whether Trump will be able to stay on top once Americans start learning more about his record and policy views. 

"When people get a chance to take a look at Mr. Trump's record and they see this guy is for single-payer health care, I think they may go, 'Well, the reality TV was pretty interesting, but single-payer health care? Not for us,'" he said, noting that back in 2007, the polls were led by Rudy Giuliani and Fred Thompson.

The candidates who do not make the top 10 will participate in a live forum hosted by Hemmer and Martha MacCallum on the same stage at 5p ET on Thursday.
