Historically, people have burned the government to the ground and started with a brand new document. I suppose that's what most people are advocating when they wish to change the constitution in a way which it does not allow.
If not by law, how is it decided? Can I decide? I suppose I can if I become a supreme court justice or someone like Bill Gates.
The founding fathers certainly knew that the constitution would be hard to change - that's the whole point. They saw what happened to past governments with wimpy foundations. I really can't see the point of keeping the constitution at all if we are going to violate it due to "current sentiments" - it's all a sham.
Perhaps they would have voted for becoming a state even without their 2 senators, but that seems far from certain to me. Like the American Revolution itself, I just can't see Wyoming people sitting down and taking what's given to them.
Of course, my predictions about the future of America are different from most. I think we've only just begun to hear the rumblings of a deep conflict. This election was not the climax, but the prologue.
