Careful bud. If you actually live in PA we are a closed primary state (something I disagree with heavily) and as such once you register as independent you are cutting yourself entirely out of the primary process in this state. My in laws are independents and nothing gets my father in law more annoyed than the reminder he can't vote on primary day unless there's a referendum. I worked the primaries last year and had to refuse over a dozen independents from voting because there was nothing for them to vote for.

Not saying you shouldn't change registration, do you. Just be aware that it's more than a self identity thing here, it comes with consequences.
