The second round of Democratic party debates has been scheduled for July 30 and 31. Similar to the first round, there will be 20 randomly selected candidates taking the stage both nights. The stages themselves will have the frontrunners in the middle.

Bernie Sanders and Elizabeth Warren, who have many overlapping policies but differ on key issues, will face off on the first night, along with Pete Buttigieg, Amy Klobuchar, Beto O’Rourke, Tim Ryan, Steve Bullock, John Hickenlooper, John Delaney and Marianne Williamson.

The second night will feature Joe Biden taking on Kamala Harris, or perhaps vice-versa, as was the case in the first round when Harris criticized the former vice president for his opposition to bussing and record of working with racists in the senate. Biden will be standing between Harris and Cory Booker, who also criticized Biden for his comments regarding his past working relationships with segregationists. The other candidates featured in the debate will be Julián Castro, Andrew Yang, Michael Bennet, Kirsten Gillibrand, Jay Inslee, Bill de Blasio and Tulsi Gabbard

Warren expressed excitement for her placement in this round. “Bernie and I have been friends for a long, long time. We’ve worked a lot of issues together,” Warren said. Warren’s numbers have been rising lately, as Bernie’s have plateaued or even dipped.
