French Socialism in a Global Era is ambitious both theoretically and empirically. Clift demonstrates a very sure theoretical and empirical touch and an impressive capacity to synthesise various literatures and apply them to different facets of Socialist Party experience. The book is rigorously researched, and also very wide-ranging. Clift demonstrates convincingly how internal party dynamics (organisational, intellectual, institutional) can mediate the effect of exogenous and endogenous changes, and very convincingly challenges some of the central presuppositions of the end of social democracy and end of history schools.
