Cuba has done great things with their nationalized healthcare, to the point where Americans will commonly vacation there for care. They eliminated mother-to-child transmission of HIV/AIDS, the first nation to do so. They have famously exported their doctors for charity work.

Cuba is a deeply impoverished nation suffering from corruption, sabotage, embargo, and they can accomplish this since they had the guts to line up a few slaveowners against a wall. It's beautiful.

Sanders is a moderate.
