Blaney and Florence C. Porter were reported to have been the first women to be delegates to any national political convention , but that distinction actually went to Therese A. Jenkins , a Republican delegate in 1892 . Asked how it felt to be the " first of their sex to cast votes in a national convention , " she replied , " I just voted , that 's all , and did not let myself be carried away by emotion at the time . " She and the other Californians were bound by state law to vote for the winner of the primary election , Theodore Roosevelt . After Roosevelt lost the nomination to William Howard Taft , Blaney became a delegate to the Progressive Party convention that nominated Roosevelt on a separate ticket . She and three other women were elected by women delegates to serve on the party 's National Committee
