Agreed. It can be much better, but it is far from terrible. From a campaign manager perspective they probably are looking at it differently. For example, there is no core theme that they are resonating on Obama. Think back to the flip/flop mantra Bush used in 2004. Everyone could have recited it. With this campaign, there is no core message resonating on the opponent. The convention had that missing. They hit him on failures, but there was no overarching take-away.
To me Cadell is over the top here. It is like ESPN when they see one game and vastly over-react in their analysis.
