First of all, Congressman Schuyler Colfax was not a Founding Father...

You've corroborated my comments on who Colfax was.

...and did not express their Original Intent.

Documentation of Madison's "expression" from the Philadelphia convention, please. I'm still waiting.

So Schuyler's opinion to Lincoln -- who was not yet President -- merely expresses the reality then happening under President Buchanan, not necessarily Colfax's views on what should happen.

Colfax isn't equivocating here. His written view is explicit:

I have an insuperable repugnance to making New Mexico a State, when,with this sovereignty, she may secede the next month as she cannot now And I look upon the Convention here next week with great distrust.

I've quoted nothing from the Philadelphia convention.
Explain what you think you are waiting for.

I'm still waiting for you to provide quotes from Founders expressing the idea that unilateral secession "at pleasure" is authorized by the new Constitution.
