What if we had the numbers to strip down the constitution and go back to the original? After 2010, I think it really could be done. With suitable modifications guaranteeing universal suffrage, there would still be opportunities to limit the federal government’s scope with airtight language (no “general welfare” clause, a much more limited “interstate commerce” clause) and perhaps add permanent limits on federal taxation and spending.
Far too dangerous. With the exception of the 17th amendment, the structure of the American government has not changed at all. And we should keep it that way.
