A “mystery” super political action committee (PAC) formed “only recently” has been exposed for dumping hundreds of thousands of dollars into a competitive Michigan Democratic primary, Punchbowl News reported Tuesday, employing tactics similar to other dark money groups later discovered to be tied to Republican operatives.The group, Michigan Sunrise PAC, has poured close to $600,000 into the race during its final stretch, and in support of progressive congressional candidate William Lawrence, while also hitting Lawrence’s Democratic opponent Matt Maasdam.“The group began airing a TV ad over the weekend slamming Maasdam as a ‘Florida Republican’ who was bankrolled by MAGA billionaires,” Punchbowl News reported. “Digital ads touted Lawrence as the best candidate to stop President Donald Trump while highlighting his endorsements from Sen. Bernie Sanders (I-Vt) and Senate candidate Abdul El-Sayed.”The group’s late involvement in the race, which Punchbowl News described as “meddling,” bore hallmarks of other dark money PACs that “meddled” in other recent Democratic primary elections, PACs that ultimately admitted to being tied to Republican operatives.“Michigan Sunrise PAC only recently filed with the FEC and won’t have to reveal its donors until after the Aug. 4 primary,” Punchbowl News’ report reads. “The group has gone to great lengths to hide its funders and operators.”In Nebraska, Maine, New Jersey, Pennsylvania and Texas, Lead Left PAC and Real Change PAC dumped around $4.4 million in May to influence Democratic primaries, and much like Michigan Sunrise PAC, “took great effort to hide their leadership and partisan affiliations,” Punchbowl News previously reported. Lead Left PAC and Real Change PAC were later discovered to have been funded by Conservative Americans PAC, a group funded by American Prosperity Alliance, a GOP-aligned nonprofit organization tied to former House Speaker Kevin McCarthy (R-CA) that advocates for conservative policies. American Prosperity Alliance made more than $22.5 million in contributions during the 2024 election cycle to various GOP-aligned PACs, according to OpenSecrets.
