Early Returns Show GOP Edge in Michigan Senate Special Election

Context The seat became vacant after former Senator Kristen McDonald Rivet joined the U.S. House in January 2025. Democrats currently hold a 19‑18 majority in the Michigan Senate. The winner will serve the remainder of McDonald Rivet’s term and run as the incumbent in the August primary.

Key Facts Initial results show Tunney with 52% of the vote, Greene at 47%, and Libertarian Ali Sledz at 2%. State Republican Party chair Jim Runestad called the race a bellwether, saying a GOP win would depress Democrats and energize Republicans. A Republican victory would create a 19‑19 tie in the Senate; although Democratic Lt. Gov. Garlin Gilchrist II would break ties, Republicans could block legislation by denying a quorum, effectively gaining veto power.

What It Means If Tunney’s lead holds, the GOP would shift the balance of power in Michigan’s Senate, forcing Democrats to negotiate or risk legislative gridlock. The outcome will test voter sentiment ahead of the 2026 midterms and signal whether recent Democratic special‑election successes can continue. Watch for final vote tallies and any legal challenges that could affect the official certification.
