Kansas and Utah are landlocked, but the contiguous "Free States" consisting of Arizona, Utah, Idaho, Montana, Wyoming, North Dakota, South Dakota, Nebraska, Kansas, Oklahoma, Texas, Missouri, Arkansas, Louisiana, West Virginia, Kentucky, Tennessee, Mississippi, Alabama, Georgia, and South Carolina are most certainly not landlocked.
Colorado and New Mexico, which supported the communist in 2008, would be landlocked if they decided to stay (or if the Free States rejected them for being too liberal), but that is not our problem. We should trade freely with them, so long as it is mutually beneficial trade and not them demanding welfare from productive citizens of the Free States. We might also consider Indiana and North Carolina, which voted for freedom in 2012, and of course Alaska, which is not geographically connected either to the Free States or to the People's Republic of Obama.
An amusing alternative - logically equivalent, but it would drive liberals who care about words crazy, would be the same division of states, but with the Free States claiming to be the United States and expelling the People's Republics from the United States. We would keep our Constitution, with a clarification that the Scalia interpretation is the only valid interpretation. The words of the Constitution mean exactly what they say, and what those words meant when the Constitution was adopted. Thus, a well-regulated militia is all able-bodied citizens, and "regulated" means trained (on their own), while that prefatory clause does not in any way restrict the individual right that shall not be infringed. Similarly, the free exercise of religion takes precedence over any parasite's feelings that might be hurt if free citizens do not want to be treated as slaves compelled to work against their will. And the rest of the Constitution also means what it says, from the Enumerated Powers to the Ninth and Tenth Amendments. We would almost certainly repeal the 17th Amendment, but that requires the full legal process, including the approval of 3/4 of the states permitted to remain in the United States.
To big an area, to many states. Go back and study what it took to get the original 13 to agree.
No, Maine does not have the votes, but we do have the firepower to secede. Living under a clinton presidency simply is not an option.
