This is not as flaky an idea as it may seem at first blush to an unimaginative conservative like you. Wyoming would be the perfect state to mass Libertarians, since it's already one of the most libertarian states, but we'd probably have to get 100,000 - 125,000 to gain a sure voting majority. I've done some research on this, and establishing residency in a state can be accomplished merely by having someplace to call home there, even if you work and spend almost all of your time somewhere else, provided you have an intent to return to Wyoming (as Dick Cheney has already proven).
If successful, Libertarians would have control of a geographically large state plus 2 Senators and a seat in the House. State laws can potentially be used to avoid the harm of federal laws, particularly with regard to federal income taxes. Moreover, if successful, neighboring states would be encouraged by the Wyoming miracle to become more libertarian, which could result in the rapid spread of libertarianism in the West (note how many states border Wyoming) and eventually throughout the country.

Very clever. I had almost forgotten about that Cheney residency thing.
