Four candidates were campaigning for governor, but only two went on to appear on the ballot in November. Rendell and Swann both were unopposed for their respective major party nominations. Constitution candidate Hagan Smith and Independent candidate Russ Diamond were unable to secure the necessary signatures to appear on the ballot. On August 11, Green Party candidate Marakay Rogers withdrew her nominating papers, following a challenge by Pennsylvania Democrats, who alleged more than 69,000 signatures on the petitions were fake names, unregistered voters or illegible.
