Just off the top of my head:

1. Wasn’t Vermont once part of New York state?
2. Wasn’t Maine once part of Massachusetts?
3. I think the boundary between Massachusetts and New York was moved sometime in the 19th century.
4. Ditto the western border of Missouri was moved from the original boundary.
5. West Virginia broke off from Virginia during the Civil War.
6. When the Dakota territory was becoming a state, it was divided into two parts , with each one admitted as a separate state.

Point being, there have been changes to state boundaries previously in American history. The idea that there can never ever be any changes to any boundaries simply is not historically true.

[Michael.SF.]

wasn't there also an issue, fairly recently in Tennessee and Georgia? A town was split in half, the boundary line was calculated in error originally and then changed?.

Missouri’s initial northwest boundary moved as well as Nevada’s eastern and southern boundaries. But they were at the expense of other territories, not states.

The Constitution allows for it however. Both state legislatures and Congress must approve.

West Virginia’s case is interesting. Congress voted for it, WVA voted for it and a rump VA legislature approved of it—VA’s legislature being ‘rump’ because of the late unpleasantness that was occurring at the time.

Allow me to throw in a few others:

Nevada was carved out of another state during the war, hence it’s motto of ‘Battle Born’.

Nevada and California has lines redrawn near Lake Tahoe due to a surveyors mistake.

And there was a battle in 1835 known as The “Toledo war” in a dispute over the state lines of Ohio & Michigan. The fact that it’s called Toledo, OH tells you who one,

And in fact, several states along the Mississippi get the state boundaries re-drawn during every spring thaw.
