The Superdelegate sytem ironically prevents the Democratic Party from actually nominating a candidate democratically. (Hillary is starting with over a third of the delegates needed for nomination before any voters have even gotten a chance to vote)
You are assuming that all super delegates will be used to sway the vote. If the margin is that large, it is highly unlikely that the Democrat party will use that much sway. Superdelegates come into real play with smaller margins, such as 55-45 or less.
It's already happened. About 480 of the 530+ who've declared have pledged for Hillary! At this rate, with less than two hundred more to weigh in, she'll only need a hair over 43 percent of actual voters to secure the nomination. It's corrupt; and laughably undemocratic. Which is why we need Sanders!
Hillary is now losing head-to-head in polling versus every Republican candidate not named Donald Trump, on whom she holds a 1% lead. Sanders is ahead of every GOP candidate. Put simply, she is more hated than any one of them by both the right & the left, & has little chance of gaining voter support.
There have been countless benign political movements that have defined themselves as socialist, but all or nearly all fascist and Nazi movements have been extremist and violent.
Most socialists do not agree. He is viewed as basically a socialist in name alone, as his usage of the term is primarily for the purpose of destigmatizing it. His policies are closer to the European Social Democrat platform, with a streak of left-libertarianism.
I've never contested that. Regardless of where his stances place him along the political spectrum, his ownership of the term "socialist" is a very important and strategic move that will help to de-stigmatize true left wing politics by removing it as a mechanism for shutting down debate.
