United Democracy Project, the super PAC affiliated with AIPAC, is spending $2 million on an initial ad buy this week to boost Rep. Haley Stevens (D-MI) in the Democratic primary for Michigan’s open Senate seat, a UDP spokesperson confirmed to Jewish Insider on Tuesday.

The new TV ad, which calls Stevens “a proven fighter for Michigan,” touts her past role as chief of staff to President Barack Obama’s auto task force, support for capping insulin prices and efforts “fighting back against” President Donald Trump’s “Medicare cuts.”

“She’s a fighter for Michigan families on affordability and jobs,” Patrick Dorton, a spokesperson for UDP, said of Stevens, a moderate pro-Israel Democrat. “We are going to show that on these ads,” he said in a statement to JI.

UDP is also spending $300,000 on radio and mail ads, Dorton said of the group’s first investment in the race. He was unable to share how much UDP intends to spend in the primary, which takes place on Aug. 4.

The spending comes as AIPAC is viewed as a lightning rod in Michigan’s closely contested Democratic Senate primary, where one of Stevens’ top rivals, Abdul El-Sayed, a vocal far-left critic of Israel, has accused her of being beholden to donors from the pro-Israel group. Mallory McMorrow, a state senator, has also vowed to reject campaign contributions from AIPAC.

In contrast with other races where UDP has relied on shell PACs that allow it to shield its involvement until after a primary has concluded, the group is spending under its own name in Michigan, which is home to a sizable Jewish community.
