Modern liberalism in the United States is the dominant version of liberalism in the United States. It combines ideas of civil liberty and equality with support for social justice and a mixed economy. According to Ian Adams, all American parties are "liberal and always have been. They reportedly espouse classical liberalism, that is a form of democratized Whig constitutionalism plus the free market. The point of difference comes with the influence of social liberalism".[1]
Economically, modern American liberalism opposes cuts to the social safety net and supports a role for government in reducing inequality, providing education, ensuring access to healthcare, regulating economic activity and protecting the natural environment.[2] This form of liberalism took shape in the 20th century United States as the franchise and other civil rights were extended to a larger class of citizens. Major examples include Theodore Roosevelt's Square Deal and New Nationalism, Woodrow Wilson's New Freedom, Franklin D. Roosevelt's New Deal, Harry S. Truman's Fair Deal, John F. Kennedy's New Frontier and Lyndon B. Johnson's Great Society.
In the first half of the 20th century, both major American parties had a conservative and a liberal wing. The conservative Northern Republicans and Southern Democrats formed the conservative coalition which dominated the Congress in the pre-Civil Rights era. As the Democrats under President Johnson began to support civil rights, the formerly Solid South, meaning solidly Democratic, became solidly Republican, except in districts with a large number of African-American voters. Since the 1960s, the Democratic Party has been considered liberal and the Republican Party has been considered conservative. As a group, liberals are referred to as the left and conservatives as the right. Starting in the 21st century, there has also been a sharp division between liberals who tend to live in denser, more heterogeneous communities and conservatives who tend to live in less dense, more homogeneous communities
