The country is divided because the government is too large. The stakes are high. You win an election and suddenly large portions of the population freak out - maybe rightly so! - because people they don’t like have power to unduly influence their life.
That is why, regardless of who wins the Presidency, Congress, or who get appointed to the Supreme Court, I want a convention of the states. There is a provision in the Constitution for it, and it would put the government back in its tiny little box.
I would be perfectly happy with dissenting states leaving the union if they so choose. I would also want **no economic retaliation** for doing so.
