Most of you already know this, but if you support Ron Paul and plan to vote for him in Arizona's upcoming presidential preference election, you must be registered as a Republican to vote for Ron Paul in the AZ primary.
If you are still registered as a Democrat or independent (or Libertarian), you won't be able to vote for him in Arizona's primary election. The deadline to switch party affiliation is tomorrow (Monday, 1/7) at midnight. If you still need to switch your party affiliation to Republican, you can do so instantly at
