Summary: Exit polling from the 2020 Mississippi Democratic primary found that 60% of voters support Medicare for All. Despite the policy having strong Democratic support, Democratic primary voters still turned out better for Joe Biden than Bernie Sanders, even though Biden did not run on Medicare for All but Sanders did. This trend was visible across several states during the 2020 Democratic Primary.
