Much more so, although the motivation for secession was due to Lincoln's decision to crack down on the "original" CSA, and not necessarily due to any love for that "peculiar institution" that states such as South Carolina and Mississippi had; ditto for North Carolina and Tennessee.
Two interesting facts about the Upper South in the CSA;
1) Many Tenneseans opposed secession, especially in the eastern parts of the state (I have no supporting figures, but I've heard an anecdote that more Tennesseans fought for the Union than for the Confederacy, despite the state's allegiance).
2) Although West Virginia was broken off from Virginia out of lack of desire for secession, the level of popular support for this is suspect due to Union troops being stationed at every poll (during the October 24th. referendum for a new Unionist state to be formed) AND given orders to arrest anybody suspected of sympathizing for the Confederacy. Given how often I see the "Stars and Bars" flying all over the state whenever I go back to visit family, I really have to call into question just how "loyal" West Virginians actually were, as opposed to leadership and public officials hand-picked by the Federal government.
