And what good is voting in the primary going to do me when the party with whom I'm registered isn't putting up a candidate I like? This year I happen to be following the Republican debate because I like those candidates better. In 2012, I might like the Democrats better. If I'm registered as a Democrat (or vice-versa) and I only like the opposing party's choices, then it doesn't matter.
The smarter thing to do would be to change your registration to the party you currently favor. That way, your voice is heard in determining that party's candidate. If you stay as an independent, you're unable to vote for candidates in either party, and let's face it - there isn't going to be a viable 3rd party candidate any time soon. Registering as an independent only serves to limit your choices.
