Except for that pesky Article IV section 2 which makes it virtually impossible for them to do so.
How are you going to abolish slavery in your state with that clause on the books? Are you going to order everyone from a slave state to stay out of your state? You can't.
You can't keep them out, and you can't order them to leave their slaves behind. You can't pass any law to take their slaves away from them so long as they are held by the laws of their own state.
So how do you make a "free" state? How do you do that without running afoul of Article IV Section 2?
I think the founders made a compromise to secure the participation of the slave states. Later, states that wished to abolish slavery, reneged on the agreement.
Total nonsense, since as you've now been informed many times, by the 1787 Constitution Convention, most Northern states had already begun abolishing slavery, and the rest would soon follow.
In the process of abolishing slavery states like Pennsylvania set time limits on how long slave holders could keep their slaves in Pennsylvania before they must either free them, or remove them from the state.
That's the law President Washington acknowledged and obeyed while living in Philadelphia.
So your claiming the Constitution required something different is pure Democrat style judicial activism.
Like Democrats you are trying to invent new law from the penumbras and emanations of a "living document" Constitution.
Sorry, but I'm telling you it just won't sell, not here.
Maybe on some Democrat site?
