At core, I see him as a manipulator. However, there are different kinds of manipulation. Some is just trickery; slieght of hand/speech with no intent other than to fool another's perceptions (people who think up ad campaigns come to mind, and, yes, definately politicians, as well as journalists- the Magician card is associated with Hermes, the Messenger/Trickster). The Magician is master of the elements (thus the 4 suits represented on his table). His is the concious, focused creative will. He will bring something into being by focusing his creative drive and talents and masterfully manipulating the elements. The results seem "magical". One kind of Magician will manipulate them toward his own ends. An earthy Magician who's own will is all, his "magic" perhaps not to be trusted, though it may just be clever entertainment. Another kind is the Magician who is in touch with the Divine (however you choose to define that, but a power beyond the physical plane). He is willing to be a conduit for the Divine will; to acheive results of benefit to more than himself.
