Gillibrand Drops Out As Stage Is Set For 3rd Democratic Debate

Kirsten Gillibrand withdrew from the 2020 presidential race after failing to qualify for the third Democratic primary debate. She plans to endorse another candidate and support the eventual nominee against President Trump. Her campaign, focused on family and women's issues, struggled against more prominent rivals and lacked national survey traction. Joe Biden leads in recent polls, contradicting earlier reports of waning enthusiasm. He, along with Elizabeth Warren and Bernie Sanders, will participate in the upcoming debate in Houston. Other candidates like Kamala Harris and Andrew Yang also qualified, while some, including Tom Steyer and Tulsi Gabbard, did not meet the polling criteria.
