Wrong. My duty is to utilize my vote in a way that I think best preserves my freedom, and the freedom of our posterity. By continuing to reward unworthy candidates with my vote, I am guaranteeing that all that will be offered is unworthy candidates. By voting my conscience and voting for a true conservative, I am not only preserving my integrity, but increasing the value of a conservative vote over time.
At times it may seem that it will take hundreds of years to "undo" what Clinton has done, but it really wouldn't take that long if Republicans started acting conservative again, if good-hearted people would do their jobs and do everything in their power to uphold the Constitution. We're seeing it happen slowly, but it isn't because of Bush or any other single personality. In fact, Bush has probably done just as much to solidify the left's ideology in the mainstream as Clinton did to motivate the conservatives to work against him. Leadership isn't figuring out where people are, and then giving them what they expect. It is doing the right thing in spite of the repercussions.
If you don't vote — for any reason — then you don't have a vote. If you don't vote against the enemy of your ideology, your are abetting them. If you let your principls trump politics, you will likely end up to be a principled runner-up (as in loser). Your opponents prefer a loser, principled or otherwise, patriotic or otherwise, with a sense of duty or otherwise.
