Social DemocracyA moderate form of socialism, in which capitalism continues to operate as society's core economic system but is heavily regulated by the democratic state, which intervenes strongly to ameliorate the social injustices that social democrats believe are endemic to unregulated free-market capitalism. Many western European nations built socio-economic systems based upon social democratic principles after World War II, but the United States never moved very far in a social democratic direction; most Americans always favored a more free-market orientation.
Universal National Health Insurance, Socialized MedicineA government-funded national healthcare system, in which individuals and employers do not purchase their own private health insurance plans because all citizens are covered by the national system.

Southern Democrats, Dixiecrat, DixiecratsMembers of the Democratic Party who reside in the South. After the Civil War, the Democratic Party held a virtual monopoly on the votes of white southerners, who resented the Republican Party for leading the North to victory in the Civil War. Southern Democrats tended to be extremely conservative, especially on issues of race and civil rights. The forging of Franklin D. Roosevelt's New Deal Coaltion—which also included many northern minorities and liberals—created serious tensions with Southern Democrats, who temporarily broke from the party in 1948 to become "Dixiecrats," then permanently flipped to become Republicans after the 1960s.
