The member of Congress who cast the sole dissenting vote against declaring war on Japan following the attack on Pearl Harbor was Jeannette Rankin, a Republican representative from Montana.12
Rankin was a committed pacifist whose opposition to the war was consistent with her earlier vote against entering World War I in 1917. Her vote on December 8, 1941, was the only dissenting voice in the House of Representatives, and it effectively ended her political career.12
