I'd send this to him if I knew how...
Dear Senator McCain,
I recognize that you are desperately trying to save a failing campaign, and a certain measure of desperation on your part is understandable. I have no problem with you going negative on Barack Obama (well I do, but I know that that's how politics works). Call him naive, call him misguided, call him inexperienced, call his ideas foolish, call him an empty suit or a celebrity. All par for the course.
But your campaign is beginning to cross the line from politics as usual into dangerous waters: you are trying to paint Senator Obama as a terrorist sympathizer and a traitor. This is maliciousness taken to a higher level. Do you truly believe that Senator Obama would welcome attacks on Americans, on American soil? Do you believe he would actively support such attacks? If you do believe this, then you should come out and say so, repeatedly, at every opportunity, because such a person should not be President. This Ayres connection is not news, it was brought up during the primaries: if this is enough to convince you that Obama is a traitor, why have you waited until now to bring it up?
If you do not believe this to be true, then be aware that you are toying with Obama's life, not just his career. You are trying to paint your opponent as an Enemy of the State, and sadly, there are a number of right-wing militias in this country, whose members may see assassination as the only way to save this country from such an Enemy. Should any of these loathsome individuals succeed, the guilt will lay partly with you and your campaign. Every time you hear a voice at a rally call out "Terrorist!" or "Traitor!", think about Senator Obama's two daughters, and do not let those calls go by sans refutation. If you are indeed an honorable man, please demonstrate it now.
Sincerely yours,
