“My policy sought only to collect the Revenue” (a 40 percent federal sales tax on imports to Southern States under the Morrill Tariff Act of 1861). A. Lincoln, 4 July 1861.
“I have no purpose, directly or in-directly, to interfere with the institution of slavery in the States where it exists. I believe I have no lawful right to do so, and I have no inclination to do so,” A. Lincoln. Inaugural address, March 1861.
That quote is not in Lincoln's address to Congress on July 4, 1861: Link
Making quotes up does not bolster your case.
“I have no purpose, directly or in-directly, to interfere with the institution of slavery in the States where it exists. I believe I have no lawful right to do so, and I have no inclination to do so,” A. Lincoln. Inaugural address, March 1861.
That at least is accurate. What's your point?
Not a sales tax, a tariff. The 1861 Morrill Tariff act applied to imports to the entire United States, not just Southern States.
