Probably a bit like Andrew Jackson, George Wallace, and Huey Long. A small but vocal contingent of nostalgic supporters who build him up to be a hero of the working man, while dismissing his many flaws as being "a product of his time" and "only for political reasons, not personal belief."
Have to agree with you there. A criticism of him (which I very much echo) would be that he is a very overrated President, but he does not have a "small group of supporters."
