Glanville received 61% of the vote to Huizenga's 39%, leading by more than 19,000 votes when the race was called. Huizenga had won the same district by just 391 votes in 2022, and advertising spending in the race approached $3 million as of late September.

Political Context
Huizenga's 391-vote margin over LaGrand in 2022 made this district one of the narrowest outcomes in that cycle. Glanville's 19,000-vote lead reverses that Republican hold with a far wider margin than the 2022 result suggested was likely.

The takeaway
Narrow legislative races can shift sharply between election cycles, so tracking district-level results helps explain changes in state government control.
