Bernie supporters and Trump supporters would say the nominating system is 'rigged'. And in some ways it is. The 'super delegate' thing is a rule put in place to prevent someone like Bernie from becoming a candidate for example.
I can't remember the candidates name, but he was a socialist and he won the Democrat nomination, he lost horribly in the general election so Democrats said no more, and implemented the super delegate rule to prevent such things from happening again.
Also in a nation of immigrants, immigrants tend to come from countries where they don't trust the government, these people believe everything about the government is 'rigged'.

More than half of American voters believe that the system U.S. political parties use to pick their candidates for the White House is "rigged" and more than two-thirds want to see the process changed, according to a Reuters/Ipsos poll.
The results echo complaints from Republican front-runner Donald Trump and Democratic challenger Bernie Sanders that the system is stacked against them in favor of candidates with close ties to their parties – a critique that has triggered a nationwide debate over whether the process is fair.
The United States is one of just a handful of countries that gives regular voters any say in who should make it onto the presidential ballot. But the state-by-state system of primaries, caucuses and conventions is complex. The contests historically were always party events, and while the popular vote has grown in influence since the mid-20th century, the parties still have considerable sway.
