Sen. Elizabeth Warren (D-MA) spoke out against the undue influence superdelegates like herself play in deciding the Democratic party’s presidential nominee.

“I’m a superdelegate and I don’t believe in superdelegates,” she told a Politico reporter Saturday at the Massachusetts State Democratic Convention in Lowell, Mass. “I don’t think superdelegates ought to sway the election.”

Warren has refrained from endorsing either Hillary Clinton or Sen. Bernie Sanders (I-VT) in the 2016 race, and her superdelegate status means she won’t have to chose a candidate until the July convention in Philadelphia.

Sanders supporters have been critical of superdelegates throughout the campaign, arguing that Democratic party leaders are unfairly aligned with the anointed nominee and unfriendly to outsider candidates.

Now that the Vermont senator trails Clinton in both delegates and votes, however, the Sanders campaign has argued it can still sway superdelegates to its side and win the nomination in Philadelphia.
