Stan, you seem to be assuming that people leaving leaving the USA because of Bush and the Republicans are doing so looking for the perfect place.That really isn't the case. I am not, and never will be, an Argentine citizen. I don't consider the politics of this place to be any of my affair.
With America, it's different. I do feel responsible for what America does. When we kidnap and torture people it's partially my fault, because these actions were sanctioned by a democratic society that I am part of , and were funded by my tax dollars. By leaving, I retain the ability to vote, but , since I can easily live on the amount of money that the US government exempts from taxes when earned abroad, I no longer support the government , and the people who enable the current government in the USA, financially. That's important to me.
