1942. Two days before the internal primaries of the Radical Party, Gabriel González Videla, who represented the Radical Party's more leftist faction, returned to Chile to dispute the nomination to Juan Antonio Ríos. The results were too close to call, so a tribunal of honor (electoral commission) was constituted, and Juan Antonio Ríos was finally proclaimed the candidate of the left-wing coalition. This Democratic Alliance () was formed by the Radical Party, the Socialist Party, the Communist Party, the Democratic Party and the Workers' Socialist Party. Ríos went on to win the general election with 56% of the votes and took office on April 2. In 1945, González Videla was elected senator for the provinces of Tarapacá and Antofagasta and represented Chile at the United Nations conference in San Francisco. 1946 presidential campaign González Videla finally won the Radical Party primaries in 1946. He attempted to revive the Democratic Alliance that brought Juan Antonio Ríos to power in 1942 but was unsuccessful in this endeavor, as the Socialist Party denounced the offer of alliance, refused to join and the popular front could not be reconstituted. In the end, González only gained a plurality with the support of his own Radical Party and the Communist Party.

Chile quickly became enmeshed in the Cold War, as Moscow and especially Washington meddled in its affairs. That friction resulted in the splitting of the CTCh (the Worker's union) in 1946 into Communist and Socialist branches and then the outlawing of the Communist Party. The Socialists were now opposed to the Communists and aligned with the American Federation of Labor-Congress of Industrial Organizations (AFL-CIO) having grown closer to United States labor interests during World War II. Once in the presidency, González Videla had a fallout with his Communist allies. They demanded more cabinet seats, which González Videla refused to grant. The Communist Party then withdrew their support for him. In response, he first expelled them from his cabinet and then banned them
