Why is the Democratic Party ignoring blue states?

In both Democratic and Republican races, there has been a lot of discussion lately of how rigged the primary system is. Both parties have been accused of ignoring the will of the voters as they prepare for their conventions over the summer. 

For Republicans, the argument is that they may decide to give the nomination to someone else instead of Donald Trump, even though he appears to be on course to have the most pledged delegates. But because he also is likely to fall short of the required 1,237 to wrap up the nominated uncontested, the argument is that you shouldn't discount the majority of Americans who actually voted against him.

But how is the system rigged for Democrats? To keep focused, I'll ignore the treatment by the Democratic National Committee and the media. But doesn't the scoreboard tell a clear picture?

First, I really don't understand why superdelegates pledge support so early in the contest since it totally skews the reported delegate count (as illustrated above). This is especially true since they can change their allegiance whenever they want, which is what many did during the 2008 election.

More relevant to me is why the superdelegates would support Clinton anyway since it is clear that Sanders has greater support in blue states and that he can tap into the large independent vote across the country (which is likely to grow if Trump is the Republican nominee). 

Take a look at the following two maps: 

• the first map shows traditional blue vs. red states based on the past four presidential elections
• the second map shows the results of primaries / caucuses through April 13th, 2016

In states that have voted Democratic in the past, Bernie Sanders is CRUSHING Hillary Clinton including double digit wins in Washington, Minnesota, Wisconsin, Vermont, New Hampshire, Maine and Hawaii. In other traditionally blue states the race was a virtual tie, including Illinois, Michigan, Massachusetts, and Iowa. Let's be clear: Hillary Clinton has not had a resounding win in any traditionally blue state. 

So how is Hillary winning the nomination? By blowing out Sanders in STATES THAT SHE HAS NO CHANCE TO WIN which make up the early stages of the primary season.

To me, that is why the system is rigged - superdelegates aligning against the states that have voted Democratic over the last four elections.
