In 1988, Willis and then-wife Demi Moore campaigned for Democratic Massachusetts Governor Michael Dukakis' Presidential bid. Four years later, he supported President George H. W. Bush for reelection and was an outspoken critic of Bill Clinton. However, in 1996, he declined to endorse Clinton's Republican opponent Bob Dole, because Dole had criticized Demi Moore for her role in the film "Striptease". Willis was an invited speaker at the 2000 Republican National Convention, and supported George W. Bush that year. He did not make any contributions or public endorsements in the 2008 presidential campaign. In several June 2007 interviews, he declared that he maintains some Republican ideologies.
