Why did the historian godfrey Hodgson referred to the postwar interaction of Republicans and democrats as a liberal consensus

The interaction between Democrats and Republicans during the postwar period was referred to by Godfrey Hodgson as a liberal consensus because after World War II, anticipating the start of the Cold War, both political parties agreed to carry forward in terms of foreign policy a liberal position that supported the development of free markets around the world, thus opposing the rise of communism and its single market policies. This, added to the internal perception caused by the memory of the Great Depression that conservative policies did not have the great results that the most liberal measures could have, made American voters turn to the Democratic Party during the 1960s.
