What the future of the "United" States of America may look like

In the Future... the nation commonly referred to as "America" will be known as "The States of America" as it's nickname.

What will this SOA look like?

It will be missing a very large chunk of it's upper Northwest and Pacific Coast. This territory would be known as The Republic of Cascadia. See here: (http://en.wikipedia.org/wiki/Cascadia_(independence_movement)#Boundaries)

There shall possibly be a large missing chunk of the midwest missing.. as the Lakotah people form their own independence inside the states of Montana, Wyoming, Nebraska, and the Dakotas. Republic of Lakotah. http://en.wikipedia.org/wiki/Republic_of_Lakotah

Vermont may be it's own country. Its Middlebury Institute has hosted the First North American Secessionist Convention. The institute has dedicated its studies to secession, separatism, and self-determination. Vermont would be known as The Second Republic of Vermont http://en.wikipedia.org/wiki/Second_Vermont_Republic

Texas is a state who's membership in the Union has a contract agreement.. it goes a little like what this guy said
"Regarding secession of a state, there is a theory about how Texas could “secede” from the United States. In the agreement with the U.S. when it became a state Texas has the right, through a vote, to divide into five separate states. It’s theorized that if this was to happen it would be challenged in the courts by the U. S., making it to the Supreme Court. It’s then theorized that they would not allow Texas to become five states, because it would give them so many seats in the Senate (ten versus two). Therefore the Supreme Court would have to deny this, which would then nullify and void the agreement that brought Texas into the union. This would allow Texas a separate nation."

If the State succeeded at this it would be known as (obviously) The Republic of Texas.

Hawaiians would protest the illegal annexation of their Republic to the Union and perhaps win.

Although no movements or actions have been recorded, The North Star Republic is an organization centered in Minneapolis, MN and advocates the idea of a socialist republic secession of Minnesota, Wisconsin, and the Northern Peninsula of Michigan.

Along with the far left, there is the far right. The League of the South is another organization going along with the rejuvenation of the Confederacy. Considering the cultural canyon between the South and most other states.. this is a possibility. Although this group is considered a hate-group by the Southern Poverty Law Center.

California could become the first state to successfully secede. As the 7th largest economy in the world (if California was considered an independent country) and plans already under the Pentagon's table for "how to deal with a Southern Californian military rebellion" there is a realistic possibility of secession. (I got that last fact from a Popular Mechanics magazine)

Combining the The California Republic with the The Republic of Cascadia.. you will notice that the entire Pacific Coast is no longer in the hands of the "New United States of America."

The Republic of Cascadia is a transnational movement which means it involves both secession from the United States AND Canada. The best way to implement this would be to secede from each country independently, then merge afterwards.

There will be a large hole in the center the United States. This is the The Republic of Lakotah.

Texas will either be partitioned into five new states, each with two seats in the Senate, giving the whole "State" a very large amount of voting power, or it will be its own independent Republic of Texas.

Not too far off would be the missing states of the Great Lakes. The economically powerful State of Minnesota combined with the welfare state of Wisconsin and the rich and exotic Northern Peninsula, are all gone from the Union in their own North Star Republic.

If the Southern states aren't missing from the map, then they are rogue states who are only "Officially" part of the United States, otherwise completely governing themselves, possibly even rejecting Federal funding.

Closer to homebase is Vermont and a possible joining of all of New England in the movement towards secession. Their liberal culture wasn't suitable for the empire.

Remembering that Hawaii is missing completes the picture.. an oddly compiled mess of the new United States. With The Cascadia Republic so close to the Lakotah republic, and bordering the California Republic, The North Star Republic only a few hundred miles from the Lakotah Republic and having waterway access to Canada, and with California's already high traffic with Hawaii, it is well foreseeable that these independent nations not only COULD exist, but that they could exist in prosperity. With the people of these regions already displaying their interests in medium scale ways.. such a futurist's predictions are well assumed.

The questions remain, will these places ever take root? Are there other republics looming in people's minds all throughout modern-day USA that are just waiting for the perfect day? How will the District of Colombia-government take all this?

No question of possibility can be answered without experience.
