When you think about some of the states borders, it doesn't make sense now, but 200 years ago there was no way of knowing how areas would develop. Take the New York City metropolitan area; it basically covers three states - New York, New Jersey and a little piece of Connecticut. When you consider the various layers of governments just related to transportation it would make more sense to form a Metro State.

It's a subject that can cover many aspects and many arguments. Then you have these little states like Rhode Island and Delaware. They could have been absorbed by surrounding states. In many ways it's more historical and traditional. To undo parts of it now would be chaotic and unrealistic. There is talk occasionally about New York City becoming it's own state just to offset the political and financial influence of the rest of the state, which has many rural and suburb areas.
