Primary Victory Secures GOP Nomination
Michael Alfonso, the son-in-law of U.S. Transportation Secretary Sean Duffy, was declared the Republican nominee for Wisconsin’s 7th Congressional District after the Associated Press called the race at 9:16 p.m. on Tuesday night. Alfonso defeated his nearest rival, former Marine and Mosinee School Board president Kevin Hermening, in a contested primary that featured six GOP candidates.
Background and District Profile
The 7th District stretches across central and northwestern Wisconsin, encompassing the Northwoods and a largely rural electorate. The seat has been held by Republicans for 15 years and has voted strongly for President Donald Trump in each of his three Wisconsin campaigns. Incumbent Rep. Tom Tiffany, who won the seat in a 2020 special election and was re-elected in 2022 and 2024, is not seeking another term as he runs for governor.
Campaign Funding and Nepotism Concerns
Alfonso’s campaign benefited from a $1 million contribution from Duffy’s prior congressional campaign account and additional donations from transportation-industry lobbyists, prompting accusations of nepotism. Critics within the GOP highlighted his recent Florida residency and his involvement in a reality-style road-trip show sponsored by companies regulated by the Transportation Department.
Reactions from Candidates and Party Leaders
President Donald Trump endorsed Alfonso in January, calling him a “MAGA Warrior.” Alfonso told reporters that the district’s three-time support for Trump reflected voters’ desire for his values, emphasizing “faith, family and freedom.” House Speaker Mike Johnson, Homeland Security Secretary Markwayne Mullin and Majority Whip Tom Emmer also endorsed Alfonso. Opponents, including Hermening and candidate Jessi Ebben, labeled the campaign “part of the swamp” and condemned perceived nepotism.
Outlook for the General Election
At 26 years old, Alfonso would be among the youngest members of Congress if elected in November. The district’s long-standing Republican lean gives the GOP nominee a strong advantage, though intra-party criticism may shape campaign dynamics as the race moves toward the general election.
