By 1908, Catt was once again at the forefront of activity. She and her co-workers developed a detailed plan to unite the various suffrage associations in New York City (and later in the entire state) in an organization modeled on political machines like Tammany Hall. In 1909, they founded the Woman Suffrage Party (WSP) at a convention attended by over a thousand delegates and alternates. By 1910, the WSP had 20,000 members and a four-room headquarters. Shaw was not entirely comfortable with the independent initiatives of the WSP, but Catt and other of its leaders remained loyal to the NAWSA, its parent organization.
