[1][2] In 1912 Mrs. Blair joined the Equal Franchise League, working for the vote for women, and in 1917 became chair of the press publicity committee for the New York State Woman Suffrage Party, which had been founded in 1909 by her friend Carrie Chapman Catt.

Her most controversial publicity stunt was dropping pro-suffrage flyers from a biplane onto President Woodrow Wilson's yacht in December 1916.

After its founding in 1920 to succeed the National American Woman Suffrage Association, she continued as a member of the League of Women Voters.

As field secretary of the club, she also addressed fire prevention, legislation to protect working women, and the creation of a national Department of Education.

[citation needed] In 1921, Mrs. Blair joined Mrs. Norman de R. Whitehouse as vice president in a firm manufacturing leather goods.
