LANSING, Mich. (AP) — A resurgent Joe Biden has continued his momentum with a win in Michigan’s Democratic primary, denying Bernie Sanders’ attempt to rekindle his presidential campaign in what will be a presidential battleground in November.

Tuesday’s primary is the largest delegate prize in this week’s slate of contests, in what effectively is a two-man race after Biden’s big Super Tuesday wins winnowed the field.

Michigan is part of the “blue wall” that flipped to Donald Trump in 2016.

Voters backed the former vice president who pointed to the auto bailout under President Barack Obama and pledged to expand health coverage.
