Michigan Democrats vote Tuesday in a closely watched Senate primary between moderate U.S. Rep. Haley Stevens and progressive favorite Abdul El-Sayed, with the winner heading to a November contest critical to the party's hopes of reclaiming the Senate majority. The campaign has become a proxy battle between the party's establishment and progressive wings. Groups backing Stevens have spent more than $50 million, including more than $30 million from AIPAC and affiliates. El-Sayed has called his campaign a love letter to Michigan. It's a Michigan moment for me, baby. The rich keep getting hyper-rich on the backs of figuring out how to monetize everyday people. I want to see a change. A critical part of my team. Crowd chant: Money out of politics! Money in your pockets!
