I'm not sure what they think they'd accomplish by amending amendment 2 anyway.
Have they paid any attention at all to states legalizing marijuana in spite of federal law?
Do they not understand that the majority of states have state constitutional protection of gun ownership, and that attempting to nullify those would be seen far and wide as a sort of breach of contract when it comes to states being a part of the union?
Do they not understand that any 'gun war' would make the drug war look like a pajama party?
They'd run out of people to grab guns long before we ran out of guns to grab, and ammunition to feed them.
