[1] She served as Political Chair of the National Woman's Party, and played a key role in putting the NWP in the media spotlight in the months leading up to the ratification of Nineteenth Amendment to the United States Constitution.

She helped Alice Paul and Lucy Burns plan their first major event–the March 3, 1913, national suffrage parade on the eve of Woodrow Wilson’s inauguration.

[7] On April 29, Baker wrote to The Suffragist on how the tour was received '[Men] invariably call out, 'Here come the Suffragettes,' but very soon they are saying, 'She's all right,' and 'That's straight lady,' or some such approving phrase..."[8] The tour culminated in a June 1916 meeting in Chicago to form what was at first called the Woman's Party of Western Voters, or Woman's Party, for short (NWP).

In February–March 1919, she served as publicity manager and speaker for the Prison Special, a three-week lecture tour by NWP activists who spoke to packed audiences about their jail experiences in an effort to generate support for the suffrage cause.

Baker's indefatigable efforts drew a great deal of media attention, and helped to normalize the presence of women in the political sphere in the public imagination.
