Several key Democratic primary races for Congress happening in metro Detroit

Voters in Michigan head to the polls on Tuesday to decide several key primary races across the state and right here in metro Detroit. In Southeast Michigan, there are three major congressional races up for a vote, some with competitors who once called each other colleagues. It comes after redistricting, which happens every 10 years due to the U.S. Census. The congressional races with three Democratic primaries are all in newly re-drawn districts.
