I've gotten that impression during the debates. He wants to play the moderate, but his need to attack authority as represented by the President gets the better of him, leading him to shrillness despite himself. He doesn't think twice about not only lying but in the process disowning his own core beliefs and values--it's obvious he's liberal but he has no problem saying he's not if it will get him elected, in contrast to a liberal who is honest enough to admit what they are. His flip-flops are symptomatic of someone who is out of touch with any reality except that which revolves around himself and his desire for attention and power.
Agreed!
