easily Democratic-Republican Party
So you would support the pro slavery party, Labor isn't states rights
If you think all democratic-republicans between 1789 and 1820 supported slavery while federalists didn't, i would suggest opening a history book, wikipedia and to inform yourself.
I am in Law School, I know my History very well even Northern D's like Franklin Pierce and James Buchanan were called Copper Head D's which means states rights and away from abolitionists. James Buchanan and Franklin Pierce were from PA and NH and didn't do a thing to stop the spread of slavery.
The Democratic-Republican party was being split in 1824. Pierce was born in 1804, not even 20 years old, back than. Buchanan was a federalist until 1824. Being in law school doesn't make you immune for stating wrong takes.
It's not wrong takes when you have Acted your History exams, that's your interpretation, you don't have a PHD in Teaching.
Democrats weren't the same back then
