WASHINGTON (AP) — Joe Biden decisively won Michigan’s Democratic presidential primary, seizing a key battleground state that helped propel Bernie Sanders’ insurgent candidacy four years ago. The former vice president’s victory there, as well as in Missouri, Mississippi and Idaho, dealt a serious blow to Sanders and substantially widened Biden’s path to the nomination.
Biden again showed strength Tuesday with working-class voters and African Americans, who are vital to winning the Democratic nomination.
Sanders won North Dakota and awaited results from Washington state. Washington’s primary was too early to call, and because all votes there are cast by mail or by dropping them off in a ballot box, many ballots were marked for candidates who have since dropped out of the race.
