Now the Bernie Sanders supporters are realizing what Donald Trump learned last month; the primary and caucuses are not very democratic. They are run by the political party elites and voter participation is not their main purpose.
Recently I ran an article on Trump's realizations that the Republican Party selection of candidates was rigged in favor of party leadership. Now Bernie supporters are realizing the same thing in the Democratic Party. The candidate selection process is rigged in their party also, designed to allow "super delegates" to act as trump cards, to over-ride a candidate the people chose in favor of a candidate that is acceptable to party leadership.
In the Wyoming caucus Sanders won a clear majority of the votes, but Hillary Clinton got the majority of the delegates. According to the Wyoming Tribute Eagle;
Violence from Sanders' people have not been happening in earlier caucuses. Many of these people are young and new to the presidential campaign system. The unfairness to Sanders has clearly upset many of them. It may not be a good course of action, but there is some logic as to why such violence broke out. People need to take back control of the political system. This is more evidence that our presidential campaigns lack real democracy and a real choice of candidates in the primary election and caucus systems. This is a major problem with having a two-party system. This is why we really need a multi-party system.
