We could pass amendments without a convention.
Specifically,
If you do the first one, you need to revisit all the programs where that is occuring and decide individually whether you want to keep them at the federal level. Without a comprehensive plan to either grandfather existing matching funds, gradually wean them off, or sunset them, that amendment will fail to pass.
I use to think that it was too dangerous as well but after recent rulings and a President that is not held accountable. Things have gotten out of hand, this system doesn't appear to be working. So does it really that it is a great document when our leaders don't follow it.
