The fourth debate was held on October 15 in Westerville, Ohio. During the debate, Yang discussed topics including impeachment, automation, the economy, taxation, foreign policy, the opioid crisis, big tech, and personal data as a property right, speaking for 8 minutes and 32 seconds, the fourth-least time of any candidate. He proposed decriminalizing opioids, a stance candidate Beto O'Rourke agreed with. Candidates Julian Castro and Tulsi Gabbard said Yang's Freedom Dividend policy "was a good idea, and something they would consider if elected president", while candidate Cory Booker argued that a $15 minimum wage was superior to UBI. Yang also spoke about the potential impeachment inquiry against Donald Trump, saying he supports impeachment, but that "we should not have illusions that impeaching Donald Trump will, one, be successful or, two, erase the problems that got him elected in 2016.
