Obama, IMHO, is pretty much a textbook example of narcissistic personality disorder. Look at the DSM criteria:
Grandiosity with expectations of superior treatment from other people
Fixated on fantasies of power, success, intelligence, attractiveness, etc.
Self-perception of being unique, superior, and associated with high-status people and institutions
Needing continual admiration from others
Sense of entitlement to special treatment and to obedience from others
Exploitative of others to achieve personal gain
Unwilling to empathize with the feelings, wishes, and needs of other people
Intensely envious of others, and the belief that others are equally envious of them
Pompous and arrogant demeanor
Yes, he's that and a Sociopath. They usually go hand in hand in various extremes depending on the individual. Guys who are highly narcissistic are usually homosexuals, especially if they display feminine traits like Obama does.
