Woodhull announces her candidacy for President by writing a letter to the editor of the New York Herald on April 2, 1870.[30]

Woodhull was nominated for President of the United States by the newly formed Equal Rights Party on May 10, 1872, at Apollo Hall, New York City. A year earlier, she had announced her intention to run. Also in 1871, she spoke publicly against the government being composed only of men; she proposed developing a new constitution and a new government a year thence.[31] Her nomination was ratified at the convention on June 6, 1872. They nominated the former slave and abolitionist leader Frederick Douglass for Vice President. He did not attend the convention and never acknowledged the nomination. He served as a presidential elector in the United States Electoral College for the State of New York. This made her the first woman candidate.
