Michigan, one of the key states that decided the 2016 election. Sanders pledged delegate count which reflected the number of votes he received from rank-and-file Democrats exceeded Clintons by four. But after the superdelegates cast their ballots, the roll call registered Clinton 76, Sanders 67
This repeated itself in other states. In Indiana, Sanders won the vote 44 to 39, but, after the super delegates had their say, Clinton was granted 46 delegates, versus Sanders 44. In New Hampshire, where Sanders won the vote by a gaping margin (60% to 38%) and set a record for the largest number of votes ever, the screen read 16 Sanders, 16 Clinton. Sanders lost those states because hundreds of superdelegates had pledged their votes long before the primaries and caucuses began.
During the New York primary, between 3 and 4 million unaffiliated voters were disenfranchised due to a statute that required changing ones party affiliation 25 days prior to the previous general election. In 2016, that deadline was 193 days before election day. Over a third of under-30 voters Sanderss core constituency werent registered to any political party. When those young people tried to vote, they were turned away.
