There are people here on FR who hate McCain and will never let an opportunity pass without expressing it.
Also, there are people who have never run a campaign and will always let you know how to run a better one.
Yeah - and when polls were good after the convention, they were mostly silent or even cheering, but now using any excuse as a justification to jump ship.
As for McCain’s comments, he had to make them. It is unfortunate that the hotheads in these crowds may have been instrumental in putting the campaign off message. The message to the public should be coming from the candidate, not the screeching from the crowd.
