Renouvin regularly publishes editorials in "Royalist", the semi-monthly of his movement, in which he professes anti-liberal doctrines.

Very close to the Count of Paris, Renouvin is close to king Simeon II of Bulgaria and his souverainism is the result of more than thirty years of public life, at the economic and social council[citation needed] and the leadership of his neo-royalist movement.

In the presidential elections 1981 and 1988, he supported François Mitterrand, candidate of French Socialist Party.

At the time of the last presidential elections (2002), Renouvin chose to support the candidature of Jean-Pierre Chevènement, only souverainist able in Renouvin's view to gather the good will of both left and right for the purpose of regaining France her position in the world.

Thus, Renouvin was also member of Pôle Républicain, a committee of different politicians across the spectrum that supported Chevènement's candidature.
