A Barack Obama ad airing in Colorado contrasts John McCain's sunny economic outlook with working people's serious problems. "How Can John McCain Fix The Economy, If He Doesn't Know It's Broken?" the ad concludes.
Marc Ambinder explains how these ads are being distributed:
As widely noticed, Barack Obama has been running tough contrast ads ... negative ads, fine... in at least a half dozen states. The campaign has taken to not informing the media of their ad buys, on purpose, so as to give themselves a few days or even hours worth of deniability and a competitive advantage.
