The way I see it, there will always be some states that matter more than others. Why not have those states be the populous ones, instead of the swing ones?
One problem though is that things aren't evenly represented,
lets look at the top 10 states by population, which make up over half the US population.
California: Only western state in the top 10, though granted, it takes up half the Pacific coast for the continential US. Primarily Democrat.
Texas: Could be considered Western because cowboys, but more midwest or maybe south. One of those multi-straddle places. Primarily Republican, though it's been getting bluer over time.
New York: NorthEast representative, NYC, primarily Democrat.
Florida: Southern representative, classical swing state.
Illinois: Great Lakes region rep, Chicago. Primarily Democrat, but I've heard pretty much everything outside of Chicago and its suburbs are Republican.
Pennsylvania: New England rep, maybe Appalachia as well. Possibly a swing state? WAS primarily Democrat and part of the 'blue wall', but I think I've read on 538 that it's been becoming more Republican.
Ohio: Great Lakes rep, typical swing state.
Michigan: Great Lakes rep, may be a swing state? It's certainly not a safe Dem state anymore and there's hardly any Dem lawmakers in the state.
Georgia: Deep South rep, Republican.
North Carolina: Deep South Rep, it
wants to be a swing state, if only the dang Republicans would let it.
The first thing I notice is that there are no midwestern plains states or the mountain states, all of which is currently 'flyover country'.
