I thank you for the back-handed compliment - even if it wasn't intended. However, I believe I am philosophically more in line with Madison than Hamilton.
"Fanatical hatred of Jeffersonianism and the spirit of republic, of the South and its defenders, and a panoply of useful lies and sand-in-the-eyes tricks."
Jefferson was a tepid constitutionalist to begin with. However, constitutional principles seemed to grow on him with age and, especially, the responsibilities of the Presidency. I think we agree he was much more of a revolutionary at heart, earlier in his life.
Neither Madison nor Jefferson condoned unilateral secession. Both would have recognized Calhounianism as contrary to republicanism.
You presume too much. Jefferson is on the record, posted to you here, as being in favor of continued union among the States, but not fanatically so. He contemplated with equanimity the possibility that some States might want to go their own way someday. That is a major point which you, I think dishonestly, attempt to gloss over here.
Madison passed over into the republican camp in later life. You presume to speak for him on the subject of the Civil War crisis.
You are just engaged in unwarrantable name-dropping now, conscribing Founders for your propaganda willy-nilly.
