I’m a fusion simply because I find it effective. We know what is required for a Constitutional amendment- 2/3rds States, 2/3rds Congress, etc, so in stead of throwing it all in initially for a Constitutional amendment, start it with State’s outlawing it, that way, you have a barometer of when you can successfully pull the federal trigger.
Exactly how I think as well. This pretty much guarantees the fed being an agent of the states like it should be.
