Former Housing and Urban Development Secretary Julián Castro has made the cut for September’s third round of Democratic primary debates, meeting polling and fundraising thresholds just a week ahead of the deadline to qualify.

Castro hit 2 percent in a CNN poll released Tuesday, paving the way for him to take the debate stage next month in Houston as the 10th candidate to qualify.

Under rules imposed this election cycle by the Democratic National Committee to whittle down an overstuffed field of White House hopefuls, candidates have until Aug. 28 to both crack 2 percent in four designated polls and sign up 130,000 unique donors.

As of Tuesday, Castro will be joined by former Vice President Joe Biden, Vermont Sen. Bernie Sanders, Massachusetts Sen. Elizabeth Warren, New Jersey Sen. Cory Booker, California Sen. Kamala Harris, Minnesota Sen. Amy Klobuchar, former Texas Rep. Beto O’Rourke, South Bend, Ind., Mayor Pete Buttigieg and businessman Andrew Yang.

Castro, whose platform includes “Medicare for All” and decriminalizing undocumented border crossings, gave a tip of the hat to his backers in a Tuesday morning tweet.

“Thank you to our growing number of supporters across the country!” wrote Castro, who also formerly served as the mayor of San Antonio.

If the field remains at 10, the next debate will be held on Sept. 12.

Should the group grow, the festivities will spill over into Sept. 13.

Those in the hunt include billionaire activist Tom Steyer, Hawaii Rep. Tulsi Gabbard and out-there fringe candidate Marianne Williamson.

All three have cleared the donor threshold, but still need to rank highly enough in one, two and four polls, respectively.

A pair of New York politicians, Sen. Kirsten Gillibrand and Big Apple Mayor Bill de Blasio, are currently among those on the outside looking in.
