I am a bit of a pragmatist about it. I WILL vote...and I will vote mostly Democratic, as I believe they come closer to what I want than anyone else. We 'should' have 4-7 parties to reflect the disparate interests in this country and govern by coalition, much like Israel.
Lacking that, our most important current goal is to prevent the co-opted Republican party from unleashing too many of the extremist wing-nuts on the world. I don't feel that any 'not-voting' protest will do anything but make it easier for those whose goal is to ensure that ALL voting with forever go THEIR way, fueled by corporate greed and faux religious piety and gun nuts...with anti-abortionists waiting in the wings to roll back womens rights a century or so.
   I will vote...and then I will harangue and push my party to better positions and with better candidates. Maybe I'll live long enough to see some progress.
