It's not just about Bernie!Well, I was raised to believe that words matter.
It's not rigged for a political party to have a process set up to favor, surprise surprise, its party. Bernie was given fair treatment within the process itself, but did not mean superdelegates had to support him. That did not mean Hillary's connections that she earned by being a party player for decades suddenly no longer mattered.
Nobody made Bernie be a Independent. He made that choice.
Given Duveger's Law and our moronic governmental design, we will basically always have two parties. In the general election, we are given two real options to choose from, and if we're rational pragmatic voters, we'll probably choose the Democrat. It doesn't matter how left or right or center the candidate is, the candidate is probably to the left of the Republican, so voting for them is the rational choice.
Now, let's say I'm frustrated with how centrist I find the Democratic leadership and would like a left alternative to them in the general election. The only way for me to affect this is a primary election. Now let's say Bernie didn't run in this primary. Clinton gets like 80% of the vote in Iowa and NH and Martin O'Malley drops out because he's not a serious candidate. The primary rolls around to my state and the option is Clinton.
Let's envision a different primary, where in addition to our current crop of candidates, Brown, Warren, Biden, Cuomo, Booker, and (insert other moderately notable Democrat) ran. While not all of these candidates are going to make it past Iowa/New Hampshire, by the time the primary finishes the party probably has had a chance to express its real preferences. This used to be totally normal and it wasn't until 2000 that we started to see the competition dry up much faster.
