Although Harry Truman had plenty of the bona fides that would indicate he was quite capable of carrying on the New Deal, it simply was not the same in the eyes of numerous New Deal veterans; to them, the late president was a swanky guy with an up-town accent and the new guy was just a square haberdasher from Palookaville:
"The crusading spirit that Franklin D. Roosevelt was able to summon up in the minds of Government employees at the outset of his first administration, and again in the years that followed, now is vanishing. The spirit and imagination of Mr. Roosevelt brought into public service would not have been there."
"But, now that the year is over, the men skilled in Government are streaming out of the federal organization into industry. Among them are hundreds of capable and highly intelligent men who really made and put into effect the decisions that kept the war agencies going... This has Mr. Truman worried."
