A significant upset has occurred in a Democratic primary. The incumbent governor's bid for another term has been ended by a challenger. This loss is notable as it marks a rare occasion where a sitting governor has been defeated in a primary. The challenger, a former executive, had previously run against the governor in a crowded primary.

The governor's administration had faced criticism over a bridge replacement project. The challenger leveraged public frustration with the project's cost and pace to argue against the governor. Further details about this primary and its outcome are available from the source.
