[Non-Sequitur]

The Constitution acts as chains on the power of fedgov; the 10th Amendment thereto insures that it shall never be reversed. Expulsion of a state by federal action would be an unenumerated power and thus the only way it can exist would be if it were necessary and proper to carry out one of the enumerated powers. It is not.

I'm not talking about Bush getting a wild hair up his butt and kicking out Massachusetts. I'm asking why the states, through a vote of their representatives in Congress, cannot expel another state? Where is that power forbidden to the states? And where is this Constitutional acid test that determines when action is 'necessary and proper' and when it is not?

A vote of their representatives in Congress would be a federal act, and thus must fall within the enumerated powers of the federal legislature.

And where is this Constitutional acid test that determines when action is 'necessary and proper' and when it is not?

The Constitutional acid test that determines when action is constitutionally derived currently lies with the Supreme Court via their usurpation of this power in Marbury v. Madison.
