All the more reason to let states and local governments do more. Rather than a unitary congress or executive that only 1/2 the people (+/-) like.
On the other hand I don't know a solve for every bill having less than a handful of votes that are bipartisan...
Like even in the abstract "here is what a voting sheet would look like" that isn't meaningfully more complex.
To be clear I think it is a hard problem and so far is the biggest detractor to alternative voting schemes.
However given all that I agree with your point that it is a meaningful path forward.
After all the federal budget is so large because you can swap states but you can't get away from the IRS.
