Electoral college. Idaho always goes red, Oregon always go blue. Moving population from Oregon to Idaho transfers electoral votes from a blue state to a red state.
Whether it matters or not depends on whether it changes the tipping point state in any given election, which is hard to know in advance, but for the red team it is at worst identical to the current setup and at best a small boost to their chances in a presidential election. Conversely for the blue team it can either be meaningless or a slight negative.

All others will pay one of these three to use their indexes, since creating and maintaining that index is incredibly expensive.
