Explanation:

The Roosevelt Progressives Party of 1912 was a political party formed by Theodore Roosevelt, after a split with the Republican Party, represented by William Howard Taft. This party became known as Bull Moose Party The Liberal Republicans was a polite party, created from the split with the Republican party. Republican oligarchs are called liberals because in the 1930s they supported the liberal policies of then-President Franklin Roosevelt of the Democratic Party, taken to recover the American economy after the Fall of 1929, also support the existence of a larger and more participatory state in the economy, advocate the existence of social programs, increase some taxes and are more tolerant of social causes such as gay marriage, abortion, gun control, tolerate illegal immigrants, oppose the death penalty, and voters in that ward are not religious . Dixiecrat is a term used in the past to designate the United States Democratic Rights Party. This party broke away from the Democratic Party in the mid-20th century to defend what it called the "southern way of life" against the oppression of the federal government.
