Then some of the southern counties could have "seceded" from West Virginia ...
... and then some of the northern townships of the "seceded" counties ...
... until, finally, Roger Snodgrass seceded from the secessionist seceded counties and formed his own country, including all four acres of the bottomland down by the river.
I have not heard too reference to individual counties (or parts of counties) seceding from a state, but one in AL did -- Winston Co. -- during the Civil War. And Lincoln did not take exception to that secession, as I recall.
Sobran is not even close to being right.
If the southern state Delegates to the Constitutional Convention wanted the right to secede - they should have put it in the Constitution.
FACT of the matter is that Mr. Snodgrass, like everyone of us, lost his individual rights to Lincoln's concept of union.
