Though I'm coming from the opposite direction, I have the same problem (not a registered Republican, but I've always voted Republican in the past). My solution is just to give up and not waste effort on politics at all. It doesn't seem like there are any options that really represent me nor any recourse to address this situation.
I'm not wanting to get to the point you are, but could see myself there soon (regarding effort on political things). I personally have never registered with either party since I perceive doing so as being part of the larger broken system problem. I haven't voted cleanly with each major political party either when it comes to all levels of elections, and my presidential vote tends to be against who I perceive to be the worst. I just wish I could see signs of the larger system changing, but this seems highly unlikely. Every time I try to dig into the little details, it always seems to come back to a flaw in the current dual party setup.
I do appreciate the discussions here much like others do, mostly for the perspective. I just don't know if I want to get to the level Tony C is with keeping up with it all, since it would just frustrate me further.
