You are asking about Jeannette Rankin of Montana. She was a Republican, and she was elected to Congress before women even had the right to vote in presidential elections. In a handful of states, however, women had been given the right to vote for representatives to Congress. Montana was one of the states that had given women this right, and that's how Jeannette Rankin was elected to the House of Representatives in November 1916, before all US women got suffrage in 1920.
