De la Torre was elected national representative for Santa Fe in 1922. In 1925, however, he announced his retirement from active politics. In 1928 the PDP was overwhelmingly defeated in the province, which moved the wannabe-governor Francisco Correa to exclaim, "We are too few to win, but too many to disappear". In 1931 the PDP entered the Democratic-Socialist Alliance, which appointed De la Torre and Nicolás Repetto for the presidential elections, but they were defeated by Agustín Pedro Justo and Julio Argentino Roca, Jr..
