Fox News projects that Bernie Sanders will defeat Hillary Clinton in Tuesday’s Wisconsin Democratic presidential primary.

With polls now closed in the state, Fox News exit polling shows Sanders will win the contest, making it his sixth victory of the last seven primaries and caucuses – and giving him significant momentum in advance of the New York primary in two weeks.

Exit polls showed Sanders won in part with the help of independent voters, who broke big for the Vermont senator.
