re: What would you like to see from a potential Convention of the States?

In addition to many of the great suggestions above:

Decentralize the Federal government, including Congress. Move all the alphabet agencies to locations far and diverse from DC and only allow liaisons, not officers or employees, to enter DC.

Move Congress out of DC and increase the House number to the proportionate figure from the original congress. It's the 21st century, they can do everything they need to do over the internet and from their constituency, and we can build a secure network for them to do it. It is ridiculous to limit the house to 435.

Anti-nepotism: close relatives not allowed to work for other agencies, some restrictions on working for NGO's and returning to Gov, i.e., expand conflict of interest. A lot of thought needs to go into this one.

Take away the prosecutorial powers of DOJ, FBI, DEA, etc. Those agencies will only be empowered to investigate and provide evidence to a state entity. All crimes prosecuted in state courts, not Federal. Special Prosecutor power for extreme cases can be granted but are constitutionally defined and limited.

States can overturn Supreme Court decisions by super majority. Federal Court authority limited to specific jurisdiction, i.e., Hawaii judge can't issue nationwide injunction.

All Federal employees, at any level, have a similar burden as our troops: a responsibility to disobey an unlawful order. It is their job to know what is unlawful.

Codify the Second Amendment as an individual right and clarify that right as universal in all states, even concealed carry.

Reinforce the Sovereignty of the States.

Limit the regulatory powers of the Federal Government.

I can think of a few others.
