A friend emailed me and had this to say:

I hate to be a moral relativist, but given the behaviour of the McCain campaign during this race, I think it would be ridiculous to argue that anything that is a factual statement about Cindy or Johnny (McCain) would be off-limits or unfair. Frank Rich points out that if Michelle were addicted to drugs, their daughter was pregnant out of wedlock, Barack had finished at the bottom of his class, Joe Biden was a complete fucking idiot, Barack and Michelle had met and apparently become engaged while each was married to someone else, Barack visited casinos at least monthly for 22 years while also purporting to oversee them - well, the election would go 100% to McCain. Instead, because the white guy is the one without morals, it's a close race.
