The third Republican presidential debate will be held on Nov. 8 in Miami, with candidates facing the toughest requirements yet to qualify to take the stage.

Candidates will have to reach 4% in multiple polls, and they'll have to have 70,000 unique donors to earn a spot in the debate, the Republican National Committee said Friday. The Republican Party has not announce who the moderators will be.

The RNC made the announcement days before candidates are to meet for their second primary debate. Former President Donald Trump skipped the first debate and will be absent from the second one, too. Instead, he plans to meet with current and former union workers in Michigan, while the Sept. 27 debate takes place at the Ronald Reagan Presidential Library in Simi Valley, California.

The requirements for the third debate will be more challenging to meet than the second. For the second debate, candidates need at least 3% in two national polls or 3% in one national poll as well as two polls from four of the early-voting states — Iowa, New Hampshire, Nevada and South Carolina, according to the RNC. The White House hopefuls must also have at least 50,000 unique donors.

The GOP hasn't confirmed the qualified participants for Wednesday's debate, but several campaigns have said they've satisfied the marks, including former Florida Gov. Ron DeSantis, former South Carolina Gov. Nikki Haley, Sen. Tim Scott, former New Jersey Gov. Chris Christie, biotech entrepreneur Vivek Ramaswamy and former Vice President Mike Pence.

North Dakota Gov. Doug Burgum and former Arkansas Gov. Asa Hutchinson participated in the first debate, but their attendance for the second is uncertain.

The candidates are arranged on stage based on their order in polls that meet standards set by the RNC, with higher-performing candidates standing closer to center stage.

Scott, who was second from the right edge of the stage for the first GOP debate last month, has proposed the RNC change how it orders the candidates for next week's debate. In a letter to Chair Ronna McDaniel, Scott's campaign argued that, since Iowa's caucus is the leadoff to GOP balloting next year, "polling results from Iowa should be the primary consideration for podium placement at the September debate."

"The debate committee has had a very thoughtful approach to the entire process, and we continue to welcome input from all candidates, partners and stakeholders," RNC officials said of Scott's proposal. "We look forward to hosting another fair and transparent debate stage in Simi Valley."
