Democratic National Committee Chairwoman Debbie Wasserman Schultz (D-Fla.) said if it was her decision, she would scrap open primaries and only allow voters registered as Democrats to participate in primaries.

"I believe that the party's nominee should be chosen — this is Debbie Wasserman Schultz's opinion — that the party's nominee should be chosen by members of the party," the Florida lawmaker said during an interview with "MSNBC Live" on Monday, according to The Washington Examiner.

States that have open primaries permit independent voters to participate in their Democratic or Republican contests.

Sen. Bernie Sanders (I-Vt.) frequently notes that his presidential campaign benefits from open primaries and that contests in which a large number of independents voters turnout help deliver him primary victories.
