Bernie Sanders’s campaign has had far more success than most people (including this guy) thought it would. He has gone from a virtually unknown Vermont senator to winning a little more than 40 percent of the national Democratic primary vote. He will probably fall short of the nomination in the end, but why has Sanders outperformed expectations so much? Here’s part of an explanation: The Democratic electorate turning out in 2016 has been a lot more liberal than it was in the last competitive Democratic primary, in 2008. CONT.
