[Non-Sequitur]

The southern senators could have defeated the Morill tariff in the Senate. They had done it before. They could have worked out a tariff compromise in the Senate. They had done it before. Instead, they seceded before the Morill tariff came up for a vote, and every compromise submitted by southern leaders - Davis, Toombs, Lechter, Hindman - all addressed the question of slavery and nothing else. If the Morill tariff was such a contentious issue then why weren't they interested in addressing that?

That's not what they all said in 1860 and 1861 when the bill was up for debate. That means it is an invention of your own.

They had done it before.

Yeah, when they had the votes to do so and the president to support them. They had neither the votes nor the president in 1861.

They could have worked out a tariff compromise in the Senate.

Not when the guys they would have been compromising with had enough votes and backing from the president to procede with whatever they wanted anyway.
