The second Democratic debate was split into two nights, with 10 candidates taking the stage on each Tuesday, July 30, and Wednesday, July 31. The big winners of the first night were Sen. Bernie Sanders and Sen. Elizabeth Warren, two progressives who made a strong case for one of their signature issues: Medicare for All . While there was no clear winner of the second night's debate, supporters of Medicare for All again had their moment, with healthcare policy being the most-discussed topic across both nights. Many of the candidates expressed their support for universal healthcare and distanced themselves from Joe Biden's anti-single-payer stance.
