There were indication that some form of United Earth was in existence over a century prior to ENT. The United Earth concept might have been slow to build, with countries joining it gradually over time. There was also something called the New United Nations, so United Earth could have had competition for members. And this would be different than many of the other states in the union how? For various section of a state not to "like each other" is common. I'm sure than after Washington's residential areas are divided between Montgomery and Prince George's counties things will be fine in just a few years. In that case, in term of population why don't we subdivide Los Angeles into sixteen states? With thirty-two senators. The New York metropolitan area could be thirty-seven states. Hell, using DC as a population standard for a state, even my little Seattle could be two states. See, the problem with DC is, it isn't a state, it's just a city, that's all it is. And Sci it's not even a very big one, Washington is something like the thirtieth largest city in the county. It has five and a half percent of the land area of the current smallest state, Rhode Island. I don't think that too many Americans want there to be five hundred states in America, with a thousand senators.
