Incumbent Democrat Kristen McDonald Rivet seeks reelection in Michigan’s 8th congressional district, a suburban and industrial seat with a Cook Partisan Voter Index of R+1. She captured the open seat in 2024 by a 6.7-point margin, and forecasters rate the 2026 contest Lean Democratic or Likely Democratic. The Republican primary on August 4 features multiple challengers but lacks a standout contender, while Rivet faces no serious Democratic opposition. Trader consensus pricing the Democratic outcome at 86 percent reflects the incumbent’s established fundraising edge, name recognition, and the district’s modest Republican tilt that has not produced a flip in recent cycles. No major developments in the past month have altered this positioning ahead of the November 3 general election.
