Results by county
Hatfield was the first Republican governor to be elected without carrying Clatsop County. That county also broke a streak of backing the statewide winner that had begun in 1906; in the next election, Clatsop County would begin another such streak that would last until 2014. As of 2026, Benton County has voted for the winner in this and every subsequent gubernatorial election.
