In that case what's the point at all? Even if Trump wins, he'll be done later. Same problem in 2024, 2028, 2032, etc.
If we can't make meaningful progress but once per generation, we should just pray and submit to God.
I'd like a more proactive and long lasting resolution, but maybe I'm a dreamer and war will get better results.
Mere mention of the legal and constitutional method is harmful? Do you have no grasp of history? Do you really just want 4 more years of Trump and that's it? Like, that's going to solve everything for ever? What fantasy do you live in?
A convention makes that irrelevant or can make it an explicitly written crime. We can enforce voter IDs, give states back their powers. A convention solves for the long-term, not just until the next election cycle (that's rigged anyway).
How could a single state have any power to do so? Take Oregon, for example. They legalized most drugs, but the Fed still has it criminalized. An amendment like this would give Oregon the ability to abrogate all federal laws regarding drugs within their state. We can see many examples where states might abrogate federal laws/regulations, related to guns, education, vehicle regulations, etc.
The effect of this shifts a lot of domestic power back to the states. Thereby making the swamp inert in one single stroke.
