re: Who is the most accomplished U.S. President.

What a lot of Americans don't realize is that in times of great stress we effectively forget The Constitution and elevate Common Sense. Lincoln was a virtual dictator during The Civil War. He had to be. The future of the nation was in jeopardy. It was clear to most everyone that The Constitution is a piece of paper. That "inalienable rights" are for the happy make-believe of peacetime. FDR got the same leverage due to not only WWII but The Great Depression before it.

Democracy may be the greatest form of government yet conceived. I can't think of a better one. But it, like anything else construed by Man, has some inherent weaknesses. Among these is its innate hinging on Compromise. When enemy forces are threatening one's shores then compromise is as unwarranted as is a shite shower. A dictatorship is better when REALITY rears its ugly head. And Lincoln and FDR got to be dictators. Therefor they got some shite done.
