Did the McCain campaign get what they paid for in Palin?

Top campaign aides to Senator McCain are complaining that Sarah Palin is not sticking to the script according to CNN. But, they said that one of her main qualifications is that she is a maverick who took on the leadership of her own party. Doesn't he fact that she won't take orders from the official campaign staff mean that she's being the maverick that they ironically want her to be?
