Bernie Sanders' bid for the Democratic presidential nomination in 2016 was not universally welcomed, to put it mildly. His basic argument was that Democrats could assemble a cross-ethnic and cross-class coalition by offering big universal public programs like Medicare-for-all and free college tuition. But large portions of the party dismissed him as an interloper, a naive radical, or even just another entitled white male. Which makes developments since the 2016 election rather interesting: Quietly but steadily, the Democratic Party is admitting that Sanders was right.
