That could have something to do with the fact that Lincoln already got the high tariff he wanted in 1861.
Obviously nonsense, as Lincoln's aim was the maintenance of the Union. If tariffs were an issue, he would have offered a course of action to address that grievance.

It was the North that introduced, and established slavery to this nation. It was they who first invested themselves by becoming slavers to a continent.
And successful they were!
To their north, the Canadian slaves were freed prior to the North's. To their south, the Confederate slaves were freed prior to the North's. Tenacious business men these yankees.
Be proud of your heritage. Honor does not require that you drag anothers heritage down to feel better about yours. On its own, the North has good reason to trumpet its practices and accomplishments. (well, maybe not its practices)
Wasn't peanut butter an invention of the North? And who doesn't like peanut butter?
He claimed it was, yet little reason exists to believe him. In fact, Alexis de Tocqueville famously predicted that if some states went to war to coerce and suppress other states, they would likely do under the "borrowed name" of the union.
If tariffs were an issue, he would have offered a course of action to address that grievance.
Not if collecting taxes were more important to The Lincoln than giving them up. Considering his obsession with collecting tariffs throughout the secession crisis, all indications suggest that they were.
