Bernie Sanders is looking to Michigan to rekindle his presidential campaign in the same way his surprise primary victory here four years ago did. The state's primary, the largest delegate prize in this week's slate of Democratic contests, also presents a resurgent Joe Biden with a chance to continue his momentum. Voters will enjoy expanded rights in the state's first major election since the approval of a 2018 constitutional amendment that has resulted in a surge of early voting which started Jan. 25. The numbers of people voting were sparse at several Detroit-area polling places. Michigan's polls close at 8 p.m.
