Shuler fought in World War I as a member of the United States Marine Corps, finishing the war with a Navy Distinguished Service Medal and the rank of captain. He was later promoted to the rank of major. On July 30, 1922, while still a captain, he commanded the detachment of four or five Marines that was dispatched by Secretary of the Interior Albert Fall to evict a drilling rig crew belonging to the Mutual Oil Company from the Teapot Dome oil field in Natrona County, Wyoming, thus precipitating one of the most notable scandals of the administration of President Warren G. Harding. The eviction proceeded without incident; the officials of the company even provided lunch to Captain Shuler and the men of his detachment after drilling operations had ceased.^[1]

Shuler ran for Congress in New York's 36th congressional district in 1920, but was defeated by Norman J. Gould. He was New York State Treasurer from 1923 to 1924, elected in 1922 but defeated for re-election in 1924 by Republican Lewis H. Pounds. He was a delegate to the 1924 Democratic National Convention.

Shuler lived at Lyons, in Wayne County, New York. He married Blanche Stewart, and they had two daughters
