So far, nine candidates have made the September debate: former Vice President Joe Biden, Sen. Bernie Sanders (I-Vt.), Sen. Elizabeth Warren (D-Mass.), Sen. Kamala Harris (D-Calif.), Sen. Cory Booker (D-N.J.), Sen. Amy Klobuchar (D-Minn.), South Bend, Ind., Mayor Pete Buttigieg, former Rep. Beto O’Rourke (D-Texas) and entrepreneur Andrew Yang.
Two other candidates, Rep. Tulsi Gabbard (D-Hawaii) and former Housing and Urban Development Secretary Julián Castro, are at least halfway there, having met the 130,000-donor benchmark but not the polling requirement of at least 2 percent support in four DNC-recognized polls.
