Red states are pretty wacked out and should probably be occupied again until they knock it off with the constant stream of crazy, especially if they are Cowboys fans.
The light blue states are largely hopeless and should only remain open for the coal mining, or The Wire, or whatever other vital national resource comes from them.
The white states are largely a toss up, but definitely swing wildly between off-the-charts craziness (remember who settled UTAH), hallucinogenic detachment (remember where all the hippies went NEW MEXICO, ARIZONA, WASHINGTON), or shoot-you-in-the-face-friend mentality (WYOMING).

How much has really changed since 1864?
