One of the most important things to realize is that if we can get a Constitutional Convention, it’s one state, one vote: ratification is by state. The big states with large populations who are dependent on government largess will no longer be in control: Nevada and Utah have the same voting weight as California and New York. The states with relatively small populations which have been fiscally responsible can amend the Constitution to prohibit the kind of welfare state that has benefited the large states that have been fiscally irresponsible. These states could even provide a mechanism for state bankruptcy for California and New York, they could prohibit public employee unions. These states could limit progressive income taxation and repeal the Reynolds v Sims/Baker v Carr line of cases that forced the states to give up their geographic upper houses.
Perhaps the founding fathers, in their genius, have left us a major ace in the hole.
