Why are Sanders delegates across the country being scrubbed from participating in the National Convention?

In many states, dually elected Sanders delegates have been prevented from becoming National delegates going to the Philadelphia Convention. We, the undersigned, believe that this maybe a strategy to weaken Sander’s position at the Philadelphia Convention We suspect foul play by the Democratic National Committee and/or Clinton campaign operatives. We do not believe for a moment that Bernie Sanders is personally aware of or has authorized these tactics.

Why is this happening? We deserve a complete explanation for what has happened to us. These are “dirty tricks” that may be violations of federal elections statutes and have no place in clean American elections.

Background: It is increasingly clear that the DNC and desperate Clinton campaign operatives are going all out to destabilize and erode any potential Sanders support at the Philadelphia Convention with obstructionist tactics. Senator Sanders is winning hearts and mind and has no need to resort to these suppressive actions. 

I also have a hard time believing that a campaign based on inclusion would seek to exclude others from the democratic process.

 All Super delegates need to be informed of these egregious matters.

I humbly wait for your reply
