Carrie Hill was president of the Equal Suffrage Association from 1898 to 1900 and remained a crucial part of the suffrage movement in Washington up to the 1910 victory, working as a lobbyist during the 1909 campaign. By July 1909, she was a leader of the Washington Political Equality League, a rival suffrage organization to WESA established after the rupture in WESA solidarity which occurred
An active Seattle club woman and wife of journalist Homer Hill, in 1887 Hill was one of a group of Seattle women organized in opposition to the ruling by the Washington Territorial Supreme Court to revoke the 1883 Suffrage Act.
The Washington Equal Suffrage Association did not start its work on the campaign for constitutional amendment ratification until January 1898.
At the January 1898 Washington Equal Suffrage Association state convention in Seattle in January, Hill was elected WESA President. Under Hill's leadership, the strategy was to work with other existing organizations for ratification. Hill, a member of the Century Club of Seattle, used the Club's efforts to prepare a pamphlet on laws related to suffrage. Hill attributed the difficulty of raising funds for the suffrage campaign to the distractions of Spanish-American War and the gold rush in Alaska (HWS, IV, pg. 973) During Hill's tenure the formation of suffrage clubs and the use of petititons increased and the support of many churches in the state was obtained. Hill also inaugurated a partial house to house canvass of voters.
Under Hill, suffragists aimed their efforts at the state’s largest cities—Seattle, Tacoma, Olympia and Spokane, distributing 5,000 copies of a 30 page booklet with testimonials from the women of the other voting states. The 1898 campaign only cost $500.00. Hill reported that Carrie Chapman Catt mailed 62,000 pieces of literature and Henry Blackwell sent 500 pieces of material to each of the counties and that the amendment had the backing of the Seattle Times, the Order of Good Templars, the WCTU and the Prohibition Party.
Mrs. Hill stated that the “liberal and free-thought societies” formed the hardest working support group for the campaign.
Despite these efforts, the vote on the amendment lost by a vote of 30,540 to 20,658 on November 5, 1898. This represented a gain of 9,510 votes in favor of suffrage over the 1889 vote. Hill blamed the failure on saloon interests.
The Washington Equal Suffrage Association all but disbanded after the dashed hopes produced by the 1898 election. Hill had worked to keep the movement alive and the Association stayed in nominal existence during the period around the turn of the 20th century and in March of 1920, as the Washington State Legislature moved to ratify the federal suffrage amendment, in the Senate, it was Mrs. Homer Hill who shared the podium with President Senator P. H. Carlyon.
