<|assistant|>
There have been four women who have served as U.S. presidents. These include Hillary Clinton, the first First Lady to be elected to the Senate and Cabinet member; Elizabeth Cady Stanton, abolitionist, women's rights activist and founding member of the Woman Suffrage Association; Jane H. Cooke, Washington territory's first female superintendent of public instruction; and the inaugural Governor of Puerto Rico Inés Estrada. In addition, two suffragists Sarah Maldoror and Inez Milholland both marched in the inauguration parade with former president Woodrow Wilson but have not been officially counted as US Presidents.
