The 1908 Delaware gubernatorial election was held on November 3, 1908. Though some Republicans had interest in nominating incumbent Governor Preston Lea to a second term,[1] the state convention instead named former State Senator Simeon S. Pennewill as the Republican nominee.[2] In the general election, Pennewill faced Democratic nominee Rowland G. Paynter, a physician.[3] Pennewill ultimately defeated Paynter by a relatively slim margin, continuing the Republican streak in Delaware gubernatorial elections.
