I vote CP and LP (I do have a few issues with LP though) whenever I can - Except when a real Conservative is running under GOP flags.
It does still happen, I am working on Joe Zarelli's 3rd Congressional District bid in Washington State. A true Conservative, even with the big R after his name.
My options are gun grabbing RINOs and/or neo-conservatives. Not many LP or Constitutional Party candidates run here. Write in or leave em blank is about all I can do, I'm done with this lesser of two evils crap.
