Aside from the fact that any law supporting slavery is reprehensible, I have no objection to the Constitution overriding state law. You miss the irony of course that when it benefited them, antebellum Southerners were all for a strong federal government. When it didnt, they were all for states rights.
Well that's interesting, because you were previously complaining about the Feds interfering with state fugitive slave laws. I simply pointed out that states could not legally, under the US Constitution, make any laws that interfered with the return of slaves.

And upon what particular event do you base this assertion? When were the Southerners calling for a stronger Federal government? I think Texas was wanting more troops on it's border with Mexico, but other than that, I'm not coming up with any examples of them wanting a stronger Federal Government.
When it didnt, they were all for states rights.
I think they were pretty much for states rights from the very beginning. They weren't all that enthralled with joining the Union in the first place. Were it not for the efforts of Francis Marion dragging the British all through the South and greatly angering them, they would have likely remained as Colonies of England.
