The Republican candidates who have qualified for the third debate

Five GOP presidential candidates have qualified for the third GOP debate on Wednesday, according to the Republican National Committee.

Why it matters: That's about half as many candidates as the first and second primary debates. Like the first two, the Miami debate is unlikely to feature frontrunner former President Trump.

Driving the news: North Dakota Gov. Doug Burgum did not qualify for Wednesday's third GOP presidential debate, per a Republican National Committee statement Monday.

• Those who qualified for the stage were listed as: Florida Gov. Ron DeSantis, former UN Ambassador Nikki Haley, businessman Vivek Ramaswamy, former New Jersey Gov. Chris Christie and South Carolina Sen. Tim Scott.

Zoom in: To qualify, candidates must poll at least 4% in two national polls or 4% in a national poll and one early state poll. The polling must be conducted on or after Sept. 1, per the RNC.

• Candidates also must have a minimum of 70,000 unique donors, with at least 200 unique donors per state or territory in at least 20 states or territories.

Flashback: Seven GOP candidates took the stage in Simi Valley, Calif. for the second Republican primary debate last month.

• South Carolina Sen. Tim Scott, North Dakota Gov. Doug Burgum and former Vice President Mike Pence have not yet appeared to qualify for the third, according to the New York Times' tracker.

Of note: Trump, the clear frontrunner in the GOP primary, has said that he will not participate in the primary debates. He counter-programmed during the first two debates earlier this year.

What's next: The debate will air at 8 p.m. ET Wednesday on NBC News and will be live-streamed on Rumble.

• Lester Holt and Kristen Welker of NBC News, and conservative talk show host Hugh Hewitt are set to moderate the debate.
