A Detroit congressman known for scandals and heavy AIPAC backing is in a tough primary fight against a democratic socialist challenger, which is bad news for the incumbent.

• Rep. Shri Thanedar, a self-funding multimillionaire, holds Michigan's 13th district after winning a split nine-way primary with just 28% of the vote.
• His challenger, state Rep. Donovan McKinney, is backed by DSA, Justice Democrats, Bernie Sanders, and most local unions, and has cleared the field into a one-on-one race.
• Thanedar carries baggage: abandoning over 100 test beagles at his old drug company, becoming a top AIPAC ally, and being the first in Congress to put campaign money into crypto.
• McKinney is running a grassroots, no-corporate-money campaign focused on a poor district where seniors choose between rent, food, and medicine.
• The race ties into a bigger Michigan fight, including a Senate primary where big-money ads falsely suggest Obama backs Haley Stevens over progressive Abdul El-Sayed.

Outlook: The primary is August 4th, and McKinney is betting organized people power can beat the incumbent's money.
