He took membership however after the 1936 elections in the Republican Federation which was moving increasingly to the right. In the 1930s Vallat was a leading representative of the Catholic, anti-Semitic extreme right in French politics. He was also anti-Protestant and anti-Masonic, arguing that Jews, Protestants and Masons were all part of a plot against Catholic France. He was violently opposed to liberalism, socialism and communism.

He favoured the project for a Latin Bloc of France, Spain, Italy and Portugal. In 1936 Léon Blum, a Jewish Socialist, became Prime Minister of France. Vallat made a series of personal rhetorical attacks on Blum, saying that "For the first time this ancient Gallo-Roman land will be governed by a Jew."
