You don’t have to be a “CSI” investigator to see that Gibbs wasn’t going to leave a trace of evidence on this one. It was a simple query: Would Obama also say that the United States will hang tough until the job is done? The press secretary, though, fended it off. And later in the briefing, he commented, “We cannot stay there forever.” That is not the Rasmussen position. That means the leaders of the two key forces in Afghanistan cannot agree on their respective dedication to the mission. Sounds awkward.
