Abdul El-Sayed and Rep. Haley Stevens will face off in the Michigan Democratic Senate primary on Aug. 4.

Democrats are in the middle of a hostile fight between Abdul El-Sayed, backed by Bernie Sanders and Alexandria Ocasio-Cortez, and Rep. Haley Stevens, the choice of Chuck Schumer.

The Michigan Senate primary race between Haley Stevens and Abdul El-Sayed reflects the Democrats’ growing ideological schism, but it’s also a contest of competing campaign styles.
