If there’s one lesson to be learned from the McCain campaign against Barack Obama, it’s this: When you put someone else down, you make yourself look awful.
McCain failed to notice the feedback he was getting from the electorate, and persisted in this pattern of attack until the bitter end. As I said in numerous interviews during the political season, one guy was running for president, one guy was running against the guy running for president. The voters preferred giving the job to the guy who wanted it.
