During the 5th party system, which group did NOT support the Democratic Party?

The Fifth Party System is the era of American national politics that began with the New Deal in 1932 under President Franklin D. Roosevelt. This era of Democratic Party-dominance emerged from the realignment of the voting blocs and interest groups supporting the Democratic Party into the New Deal coalition, following the Great Depression, with most black voters switching from the GOP to the Democratic Party and most conservative, white southern Democrats shifting to the Republican Party as the Democratic party became known as the party of civil rights.[1] For this reason, it is often called the "New Deal Party System". It followed the Fourth Party System, usually called the Progressive Era, and was followed by the Sixth Party System. However, the beginning of the Sixth Party System is disputed.
