If two of the smartest people on the political Internets cannot discern any identifiable "clear message" coming from the Obama campaign how will the typical low/medium information voter figure it out?
From Obama, honestly, I don't sense a really clear message. There are attacks on McCain, some of which are quite good. There are positive uplifting commercials. And there are ads/messages targeted to particular states -- like Yucca Mountain in Nevada and the DHL layoffs in Ohio. But it's hard for me to come up with a clear cut Obama message in way that it's pretty simple for me to do with McCain. Even the 'change' message, which is the basis of Obama's campaign, seems much more diffuse to me than it was during the primaries.
...the central problem for the campaign is that nobody knows what Obama stands for. It's a perennial problem for Democrats, but I think it may be an even bigger problem this time. The hope and change theme was galvanizing in the beginning but it isn't enough to sustain full campaign. What was once inspiring has become a fog.
