If you can point to a clause that prohibits a state from being expelled from the Union against its will.

The states were bound by their own VOLUNTARY act.

Is being thrown out *voluntary*?

DUH...It's being forced to leave against your will!

[Non-Sequitur]

The states were bound by their own VOLUNTARY act.

What's voluntary? States don't join the Union, they are admitted. And, constitutionally, they can be admitted without any input from the people in the territory at all. Likewise, the people of the territory can petition till the cows come home and they will become a state only when Congress allows them to.

DUH...It's being forced to leave against your will!

DUH...and where does the Constitution say that the states cannot do that?
