The whole thing is absurd and overly represents rural areas and Republicans. We already have a huge problem with the "2 senators per state" thing and the House representing Republicans far too much in relation to their numbers.
But but but why should cities get to determine everything? Don't you know that not only does land vote, everyone in a patch of land votes the same? So, why bother giving everyone in a city a vote, you know?
Also, be sure to let the vice president cancel the whole thing if they don't like the results.
We should just abolish the Senate. With the current formulation of the US government there's no reason why a State should have extra power like that. Let the people make the rules. Expand the House, abolish the Senate, and remove the electoral college. And since we're wishing for things that will never happen anyway, go ahead and use some kind of proportional vote (ranked choice, star, whatever, just literally anything but FPTP).
