François Bayrou has been a vocal campaigner on a variety of issues, including reform of the political process, civil liberties, and free software (see DADVSI). During the 2007 presidential election campaign he described the European Union as "the most beautiful construction of all humanity". He called for France to play a greater role in the European Union's affairs, and supports the ratification of a European Constitution, in a more concise and readable form than the one voted down by the French electorate in 2005.
