Candidates need four national polls showing 10 percent or higher support or 12 percent or more in two single-state polls of Nevada and South Carolina. They have until 11:59 p.m. on Feb. 18 to qualify for the debate, which is being hosted by NBC News, MSNBC and the Nevada Independent.
Candidates can also qualify by winning at least one delegate from the Iowa caucus or the New Hampshire primary. To date, former Vice President Joe Biden, former South Bend, Indiana, Mayor Pete Buttigieg, and Sens. Amy Klobuchar, D-Minn., Bernie Sanders, I-Vt., and Elizabeth Warren, D-Mass., have all qualified for the stage, according to an unofficial NBC News survey.
