.....expel the New England States......
I have used the word purge, but expel conveys the same thought.
You have proposed a legal method for achieving the objective.
That will take forever and requires the expelee’s consent. A better way is to drive them from the congress and simply tell them to be gone, they are no longer welcome, the places the represent are no longer part of the Union.
The force of arms is more effective than the fig leaf of law
Why? If a state can leave without the consent of the other states then why can't the other states expel a single state without its consent?
A better way is to drive them from the congress and simply tell them to be gone, they are no longer welcome, the places the represent are no longer part of the Union.
And that differs from expelling how?
