Michael Alfonso, 26, is not just another name on the ballot in Wisconsin’s 7th Congressional District. The son-in-law of U.S. Transportation Secretary Sean Duffy has quickly become one of the top contenders in a crowded Republican primary, turning the race into a tug-of-war over clout versus seasoning. Big-name endorsements and seven-figure outside spending have fired up some Republican voters, even as long-time party hands grumble that the contest is being engineered from afar instead of built from the ground up.
Money and endorsements
Duffy has funneled $1 million from his old House campaign account into a super PAC boosting Alfonso, and that committee has also pulled in a separate $1 million check from GOP megadonor Richard Uihlein, according to the AP. On the other side of the family ledger, Elizabeth Uihlein has routed a different seven-figure contribution to a PAC backing rival Jessi Ebben, who has also drawn support from conservative organizations including the Club for Growth PAC. Former President Donald Trump has weighed in for Alfonso as well, an endorsement his campaign has loudly promoted as it tries to lock down Republican voters.
Local backlash
Across the sprawling, heavily rural 7th District, long-serving Republican officials have not been shy about their discomfort with the tidal wave of outside cash and Duffy’s high-profile role. County party chairs and veteran activists told Wisconsin Public Radio they fear Alfonso’s relative youth, combined with a top-down push from national figures and megadonors, is crowding out the retail politicking and local relationship-building that usually decide races in northern Wisconsin.
Transportation donors and ethics concerns
Scrutiny has also zeroed in on who is helping fund Alfonso’s rise. Reporting by ProPublica found that a notable share of his outside backing has come from transportation industry executives and lobbyists with business before the Department of Transportation. Legal experts told the outlet that, even if the contributions comply with campaign finance law, they create a sharp appearance-of-conflict given Duffy’s Cabinet role. ProPublica also reported that Duffy has appeared on the trail with his son-in-law; the transportation secretary’s office responded that he attends campaign events in a personal capacity and that regulatory decisions are made by career staff in accordance with the law.
The race ahead
The Republican primary is scheduled for August 11, 2026, and in a district that has reliably voted red in recent years, whoever emerges from that contest is overwhelmingly favored to win in November. Rivals such as Kevin Hermening, a local veteran and long-time party operative, along with Jessi Ebben and Niina Baum, are pressing voters to weigh their experience and claimed independence against Alfonso’s famous backers and the national spotlight trailing his campaign, according to official election information compiled by The Green Papers.
