"...FDR should be up there because of leadership during times when our country was engaged in major wars that threatened our national existence"
FDR was laid up in bed most of the time our "greatest generation" was out fighting the war that he promised to keep us out of - before prodding Japan into dragging us in.
Then he turned half of Europe over to Stalin in exchange for his "united nations" fantasy, starting the cold war and leaving us answering to France as his legacy.
