Alfonso Wins GOP Primary for Wisconsin’s 7th Congressional District

Michael Alfonso, a 26‑year‑old political newcomer and son‑in‑law of Transportation Secretary Sean Duffy, is projected to win the Republican primary for Wisconsin’s open 7th Congressional District, Decision Desk HQ reports. The seat, which has been held by the Duffy family for years, is up for grabs after the incumbent announced retirement, prompting a crowded field of candidates.

Alfonso’s candidacy has been buoyed by high‑profile endorsements, most notably from former President Donald Trump and his father‑in‑law, who served the district for nearly two decades. His youth and outsider status contrast with the more seasoned candidates, while the Trump endorsement has helped him secure early momentum in the primary race. Decision Desk HQ’s analysis points to a combination of name recognition, party support, and campaign organization as key factors in his projected lead.

If Alfonso secures the Republican nomination, he would become the next representative for the district, a role that has historically leaned strongly toward the GOP. The outcome of the primary could signal a continuation of the district’s conservative alignment, while also highlighting the influence of national figures and family ties in shaping local electoral prospects.
