Akhil Reed Amar writes in Myth America about the founding fathers. He emphasizes Washington's importance to the Constitutional Convention and downplays Madison's contribution, sees little difference between "republican" and "democratic", emphasizes the "union" side of the founding, doesn't accept Charles Beard's interpretation, and accepts the Constitution as helping slavery.
All in all it seems well-argued. I was surprised by his singling out Beard; by 1960 he seemed no longer prominent.
