You're the one that called McCain's comments a smear. I asked you if McCain's comments are true, are they still a smear? What is vague about that? The comments can't be a smear and not be a smear at the same time can they? Its very specific, not vague at all, if the particular words of McCain that you called a smear are factual, are they a smear?

Have you ever heard the left say anything about George W. Bush that was a smear? If so, what?

Have any Obama/Biden supporters said anything about McCain or Palin you would characterize as a smear? How about the ad attacking McCain about email that Obama approved which Biden called "terrible."

You could just end this and admit you're applying a double standard - that anything damaging, true or not, said about Obama/Biden is a smear, and anything, regardless how nasty, untrue, or irrelevant, said about those you want to see defeated is ok with you.
