Answer:
The philosophy of the democrats was, at the beginning, of social conservatism and economic liberalism, with populism as its main characteristic in the rural areas of the southern United States. Beginning with the New Deal Coalition of Franklin D. Roosevelt in the 1930s, the Democratic Party has also promoted a liberal social platform, supporting social justice. Thanks to the New Deal, the party's conservative wing became extinct outside the South. The New Deal Coalition from 1932 to 1964 attracted strong support from voters with recent European origins, many of whom were Catholics living in large cities. After the racial upheaval of the 1960s, most of the white southerners and Catholics from the north changed their ideologies to the Republican Party at the presidential level, as they felt that the Democratic Party no longer represented their values.
The transformation of the Deep South into a Republican force was effectively completed after the Republican Revolution of 1994, which allowed Republicans to win seats in Congress throughout the country. In 2005, Georgia Senator Zell Miller, considered the last conservative traditional Democratic Southeast, got retired.
