Four female journalists will moderate the Democratic primary debate next month in Georgia, including a repeat appearance by the star commentator Rachel Maddow, NBC News said on Wednesday.

Ms. Maddow, who was a moderator at the Democratic debate in June, will be joined by the veteran NBC News correspondent Andrea Mitchell and a pair of prominent White House correspondents: Ashley Parker of The Washington Post and Kristen Welker of NBC News.

The debate, jointly sponsored by MSNBC and The Post, is scheduled for Nov. 20. Eight presidential candidates, so far, have clinched a spot onstage. Candidates have until Nov. 13 to meet the Democratic Party’s thresholds for fund-raising and polling performance.

Ms. Parker, who previously covered politics for The New York Times, will be the second print journalist to moderate a primary debate this year. Marc Lacey, the national editor of The Times, appeared alongside two CNN anchors at the Ohio debate this month.
