> <50% want to do the necessary ground-work of "cutting Wyoming down to 0.2 senators".
No, that's not the case. I'd dare say >50% of the population wants to cut Wyoming down to 0.2 senators. But how do they accomplish that? The only viable route is a constitutional amendment. For that to pass, you need 2/3s of the senate to agree AND you need 3/4s of the states to ratify.
By saying "oh, well the majority can just insist on the change" ignores the fact that the current system gives the minority power to say no.
The only hard work the majority could actually do is move from these high population states into low population states to re-balance the voting power.
The US is not a democracy. 50% of the population wanting something means nothing. And without an actual civil war and new constitution, that won't change.
