Actually, they (and you) are the ones worked up in the lather. I'm just bursting their self-delusional bubble, if the candidate they vote for for "conscience's sake" can only muster an infinitessimal level of support, and a Democrat wins for their having done so.
Their actions will only dilute the vote of those other basically like-minded individuals who if by sticking together can actually make a difference in bringing to pass the principals they all so "righteously" claim to champion and claim to hold dear.
You can take that point up with all your other disaffected "conservative" friends. The Dems never had better allies.
