A behind-the-scenes establishment push in Michigan's Democratic Senate primary could backfire, bad news for party unity and possibly for Democrats in 2026.

• Schumer is quietly asking donors to back moderate Haley Stevens over progressive Abdul El-Sayed.
• El-Sayed is rising in the polls and just won the powerful UAW union's endorsement.
• Pro-Israel PACs have poured millions into backing Stevens, making Israel a wedge issue in the race.
• Stevens stumbled in a recent debate, dodging questions about her AIPAC-linked donors.
• The fear: if Stevens wins the primary, frustrated progressive voters may stay home in November, like many did when Harris lost Michigan.

Outlook: The primary runs until August 4th, with El-Sayed holding a slight edge and plenty of campaigning left.
