Oyster Bay Progressives (Cherry, Plum, and Chrysanthemum)

Oyster Bay Progressives was the designation for the members of Progressive Party whose opposed the nomination of Franklin D. Roosevelt in 1932 and supported Theodore Roosevelt, Jr. instead. They were named after Oyster Bay, New York, the place of origin of Theodore Roosevelt's branch of Roosevelt family. They were also called the Old Bull Mooses. Their opponent was the Hyde Park Progressives, named after the place of origin of Franklin D. Roosevelt's family belonged.

Like the New Dealers, the Old Bull Mooses favored the protection of civil rights and advance of "local and direct democracy" and supported social welfare programs. However, they generally criticized the New Deal as ineffective and risked political corruption. On other hand, the Old Bull Mooses were conservative in social policy, following the principle of communitarianism and respecting traditional American values over cultural pluralism. Some of the Old Bull Mooses were also staunch isolationists and opposed the American entry to World War II.

The strong political bases of Oyster Bay Progressives were in upstate New York, Washington and South Dakota. Although the labor unions mostly supported the Hyde Park Progressives, the leader of United Mine Workers' Association (UMWA), John L. Lewis, was famously identified as an Oyster Bay Progressive following his quarrel over the labor policies with President Franklin D. Roosevelt. Many of Old Bull Mooses were former members of Republican Party whose supported Theodore Roosevelt in 1912 and 1916.
