schools of thought within American conservatism. Social conservatives and the Christian right advocate traditional values, decentralization, and religious law, fearing that the United States is undergoing moral decline. Fiscal conservatives (or classical liberals) advocate small government, tax cuts, and lower government spending. Americans that identify as conservative will typically support most or all of these ideas to some extent, arguing that small government and traditional values are closely linked. Other conservative ideologies typically support isolationism and limited involvement in foreign affairs. American right-wing populists advocate tax cuts, protectionism, and opposition to immigration, framing politics as a battle against "elites" from above and "subversives" from below. Conservatism in the United States does not advocate a unified foreign policy ideology, though common tenets include support for American hegemony, promotion of free markets abroad, and combat readiness. Realism was prominent in conservative foreign policy during the mid-20th century, advocating cautious advances in influence through diplomacy to advance American interests. Support for realism fell among conservatives during the Reagan administration in favor of American exceptionalism and more aggressive anti-communism. Neoconservatives form an interventionist wing of the conservative movement, advocating peace through strength and the use of force to promote democracy and combat threats abroad. As of 2021, over one-third of the American public self-identifies as conservative. The Republican Party represents conservatives in the United States, with 74% of Republicans identifying as conservative, compared to only 12% of Democrats. As of 2022, Republican leaning voters are more likely than Democrats to prioritize the issues of immigration, the budget deficit, and strengthening the military. A Pew Research study in 2015 found that the most reliable Republican demographics were Mormons and Evangelicals, particularly white Americans in each group. Liberalism Modern liberalism in the United States originates from the reforms advocated by the progressive movement of the early 20th century. Franklin D. Roosevelt implemented the New Deal in response to the Great Depression, and the New Deal programs defined social liberalism in the United States, establishing it as a major ideology. In the 1960s, it expanded to include support for the civil rights movement. Following the rise of the Reagan coalition in the 1980s and the shift toward conservatism in the United States, American liberals adopted Third Way liberalism. A movement of left-wing populism emerged within liberalism following the Great Recession and Occupy Wall Street. Liberalism in the United States is founded on support for strong civil liberties,
