In 2005, Pratte was among the group who signed the manifesto "For a clear-eyed vision of Quebec", better known by the French title "Pour un Québec lucide" and critical of the social democratic 'Quebec Model'. Criticized by some sovereigntists, he has defended his neutrality and has claimed in the book "Aux pays des merveilles" to be a soft-nationalist and to have a soft-sovereigntist past (with claims of 'Yes' votes in both the 1980 and the 1995 Quebec referendums).
