Davis was not an "idiot" but he was hobbled by his extreme loyalty to those he considered his friends or allies. That loyalty, while a desirable trait if done in moderation, set the stage for Davis' dealings with those he favored (e.g., Bragg, Pemberton, Polk), and those he disfavored (e.g., Beauregard, Johnston) regardless of their specific military strengths and weaknesses. There is certainly blame to go around for subordinates who had their own agendas, and whose attempts to undermine Bragg may have bordered on being mutinous. It should be noted that the Union armies were not entirely free of command conflict and dissension as was the case with Burnside and Hooker particularly. But the leadership flaw in the AoT was especially unique and extreme, and for that Bragg must be accountable for a good portion of it.
