In 2007, Cunningham endorsed Hillary Clinton in her campaign for U.S. President. In April 2008, Cunningham was the top vote-getter in the 15th congressional district to serve as a delegate Hillary Clinton to the 2008 Democratic National Convention. Cunningham announced as early as 2007 that he was considering a run for Pennsylvania governor in 2010. However, in June 2009, he announced he would not seek the post due to family concerns and time restraint. Cunningham had raised about $725,000 for the possible campaign by that point.
