Go get him, Swiftees!
I am glad that I am not supporting Bush. If I was, and the best campaign issue I could come up with was questioning the details of Kerry's combat medals while my guy wasn't even there, I would feel pretty foolish.
If this is the big campaign issue, then the libertarian assertion that there is no substantive difference between them is valid and the only possible candidate to vote for is Badnarik.
You are not wasting a vote when you refuse to choose between two evil candidates.
