The United States, as a relationship between people, has been failing for several decades now. Just like Rome wasn't built in a day, it didn't fall in one either. An election isn't going to change the fact that whatever relationship was being described by "The United States of America" is effectively finished, but it can be a useful way of cushioning the landing so that the people who live here (citizens or not) can support each other and live more freely.

If my vote is marginalized by wherever I'm living, then I don't see any good reason to support somebody who's going to continue slapping duct-tape on the deadly project of American capitalism.

If my vote might actually mean something, then the principle of protecting the people who live here wins.
