Several states and millions of Democratic voters have not yet had a chance to cast their votes.

We respect those voters and believe that they, like the voters in the states that have already participated, have a right to be heard. None of us should make declarative statements that diminish the importance of their voices and their votes. We are writing to say we believe your remarks on ABC News This Week on March 16th did just that.

During your appearance, you suggested super-delegates have an obligation to support the candidate who leads in the pledged delegate count as of June 3rd, whether that lead be by 500 delegates or 2. This is an untenable position that runs counter to the party's intent in establishing super-delegates in 1984 as well as your own comments recorded in The Hill ten days earlier:

"I believe super-delegates have to use their own judgment and there will be many equities that they have to weigh when they make the decision. Their own belief and who they think will be the best president, who they think can win, how their own region voted, and their own responsibility."
