In 1860 they were Democrats, allied to Southern slavers to rule over Washington, DC, since the election of 1800. If what you are saying was true, the tariffs would have been 13% as the Confederate states made them, and the Congress would have voted to allow slavery in the territories.
Clearly none of that happened, so clearly you are wrong. Washington DC was controlled by Big City Northern Liberals, and it is still controlled by Big City Northern Liberals.

"If what you are saying was true, the tariffs would have been 13% as the Confederate states made them, and the Congress would have voted to allow slavery in the territories." But tariffs were lowered to 13% in 1857 and remained there until Southern Democrats seceded and walked out of Congress in 1861.
And Congress did allow slavery in the territories.
"In the Compromise of 1850, it was decided that New Mexico Territory would be able to choose its own stance on slavery by popular sovereignty.
In 1859, New Mexico passed the Act for the Protection of Slave Property. "
Other western territories like Oklahoma, Utah & Colorado also allowed slavery until Congress outlawed it, during the Civil War.
So, thanks for making my point!
