I can't vote for Dr. Paul next year; I'm not an American citizen. But if I could, I would. Because, as Vox Day so aptly puts it (my emphasis):
The choice is simple. If you want to live under an EU-style regime that is intent on invading and occupying other countries in the name of democracy for the foreseeable future, vote for any of the so-called major candidates. It doesn't matter which one.[...] If, on the other hand, you wish to live in a nation where the United States government is governed by the Constitution, you had better support Ron Paul. This may be your only opportunity, for it is entirely possible that this will be the last time such a choice is presented to you.
