What on earth was John McCain thinking, in agreeing to do a SNL spot 35 minutes into the show? The run-into-the-ground "joke" line was, "I am older than anyone can possibly believe. Hardee-har! I am so incredibly old!" Jeesh. He came across as a good sport, but, well, old. Everyone has seen SNL items that could be used as campaign ads. This is the only one I can think of where a candidate intentionally produced something that could be used as an attack ad on himself.I get it: McCain was trying to defuse the age issue, which he knows is festering away out there. But this didn't defuse it. It just introduced it to a whole new audience. Dumb.
