Incumbent Republican Rep. Tim Walberg, who filed for re-election on April 20 as the sole GOP primary candidate, commands trader consensus at 90.5% implied probability of a party win in solidly conservative MI-05 (Cook PVI R+13), buoyed by his 65.7% victory margin over Democrat Libbi Urban in 2024 and $950,000 cash-on-hand edge as of late March over presumptive Democratic nominee Christian Vukasovich's $9,500. All major forecasters rate the seat Safe or Solid Republican ahead of the August 4 primary and November 3 general election. While entrenched incumbency and district lean drive the lopsided odds, a Walberg scandal, health issue, retirement announcement, or national Democratic wave could narrow the gap.
