Honestly, unless we change our electoral college and the way that Senators represent people, which are things that we should totally do, we should break up our most populous states into smaller states. I would say that should be our first goal for new states.

States with large populations ironically have less proportional representation in the Senate, and they have fewer electors, per capita, in the presidential elections. In other words, in populous states like California, Texas, and Florida, the voters have less representation than if they lived in Wyoming.

Plus, the Senators and electors are generally winner-take-all, which means that, if you compare to a multiple state solution, the minorities in those states are essentially disenfranchised completely.

So, with such a large discrepancy in population between the most and least populous states, countless voters are getting screwed under our current system.

The only people who benefit from large, populous states are people who are leaders of some sort in those states. The governors of Texas and California have power over many more people than the governor of Alaska. Wealthy people get more if they buy a state politician in Texas than in Vermont.

It would make more sense to split some states up and maybe merge other states together until there is at least some pretense that each state has a similar population.
