Thomas Smith, a retired General Motors engineer, won Michigan’s 8th Congressional District Republican primary on August 4 with 50% of the vote, defeating Amir Hassan, a former federal law enforcement officer backed by President Trump who received 33%, according to the Detroit News and multiple news outlets.
Smith’s victory is striking because he had suspended his campaign in mid-July but remained on the ballot after the withdrawal deadline had passed. When Smith withdrew, he endorsed Al Lemmo, the third candidate in the race who finished with 16% of the vote.

The Michigan 8th District, which spans Saginaw Bay and includes Flint, Saginaw, Bay City, and Midland, is a key battleground. Cook Political Report rates the district as Lean Democratic, and incumbent Democrat Kristen McDonald Rivet won the seat in 2024. Smith will now face Rivet in the November 3 general election, though his surprise primary win complicates Republican efforts to flip the seat.
Hassan’s loss extends a pattern of Trump-endorsed candidates struggling in 2026 primaries. According to reporting from The Hill, Hassan’s defeat added to what outlets described as a string of the president’s primary losses this cycle. NBC News noted that Smith, described as a political unknown who raised almost no money for his campaign, defeated Trump’s preferred candidate in a purple district where the outcome could help determine control of the House.

Smith’s acceptance of the nomination despite his earlier withdrawal raised questions about the general election strategy for Republicans in a district Trump won but which has trended Democratic in recent cycles. The unexpected result underscores the unpredictability of primary races even when a sitting president backs a candidate.
