I too, have enjoyed the discussion.
As to the original intent of the Founders being, specifically, that the judiciary should strike down unconstitutional acts of Congress (Marbury v. Madison), I refer you to The Federalist No. 78, which describes this in painstaking, clear, and for those who say the Founders didn't intend the Supreme Court to have judicial review power, alarming detail.
Hamilton, Madison and Jay certainly thought, in 1788, that were the Constitution ratified, the Supreme Court created under it would have the power that John Marshall said it did in 1802,and to which Jefferson acquiesced.
