Obama is never better than when he's intellectually indignant. This was true on negotiating with dictators. It was true on the gas tax holiday. And it's proving true on tire gauges. If I were on the Obama campaign, the themes laid out in this video wouldn't simply be my rejoinder to the GOP's tire gauge bullshit. They'd be my message for the next few months. Not only is there a cutting attack in here, but there's also a reply to McCain's charges that Obama lacks substance. After all, if McCain has so much substance, how come he doesn't actually know anything?
