I just blogged, in The Huffington Post a piece to that effect, where I discuss ongoing unsavory behavior among the influence peddlers handling McCain, and suggest that he needs to be himself:
You look closely at the people pulling the strings on McCain, and you can see that his campaign is run by influence peddlers. He is being fed scripts by hacks that have managed to exploit registration loopholes, while the legitimate lobbyists on his campaign team are being asked to step-aside. The most influential members of McCain's entourage now include people like Charlie Black, McCain's Senior Political Advisor, whose firm has represented shady characters like Philippine dictator Ferdinand Marcos as well as unscrupulous private security contractors such as Blackwater Worldwide.
I feel that people who claim that McCain is "confused" are not looking at the whole picture. When you're trying hard to recite memorized lines, it's easy to confuse facts like Shia vs. Sunni Muslims, or the actual vs. the predicted affect of the new GI Bill. This isn't genuine confusion; it's just hard to remember lines, especially when they go against your better judgment.
