I don't think you've compromised (as a dirty word), I just think you're mistaken in your evaluation of the candidates. As I've pointed out on another thread today, different reasonable folks can react differently to the same information.
To a certain degree, we all compromise on a candidate (though some folks delude themselves into believing they've found a "perfect" candidate) -- the only way to perfectly represent yourself would be to run yourself, and that's assuming you would never compromise, even a little, on a principle to achieve a pragmatic result.
If you cloned me, I probably wouldn’t vote for my clone. :-)
