Since the Morrill bill was the point of contention on the tariff issue...
Seven states published secession documents before the Morrill tariff passed.

That's a marxist fib, Walt. You've been shown this before. The Morrill tariff passed in two stages - one in the House, one in the Senate. It passed the House on a strictly sectional vote months before any state seceded. That was in May 1860.
By November 1860 The Lincoln had been elected and he was pledging to push the protectionist tariff through. He told one audience that it would be the single most important issue of the next congressional session if it did not pass before then.
With the bill already through the House and having the support of the incoming president, the only thing in its way by the time secession started was the evenly split Senate...and Lincoln's asserted priorities made it clear he was going to force protectionism through that senate. It passed the Senate a few days before his inauguration.
