(Not a political statement.)
Have you ever noticed that the states get bigger and bigger, basically in the order that they were created?
The original thirteen are rather small and the others gradually grow, generally speaking, as they progress down and over to the west.
It's a lot like if I were drawing a pattern of stars and got tired of creating all that detail. (I'm right-handed, so it goes left.)
Did the early settlers also think, "What a pain. We'll just make 'em bigger as we go..."
