At an August 27, 2007, peace rally in Kennebunkport, Maine, McKinney confirmed the depth of her disenchantment with the Democratic Party, urging San Francisco voters to replace Nancy Pelosi with antiwar activist Cindy Sheehan. On September 10, in a letter to the steering committee of the Green Party of the United States, McKinney stated she would not seek the Green Party nomination for president. However, in early October it appeared that McKinney was making moves toward declaring herself an official Green Party candidate.
