Scary thought. He may not be THE Anti-Christ but there is certainly a pattern / archtype seen throughout history. Almost like the forces of evil "testing the water" before plunging in whole-heartedly in the battle against God. IMHO Obama has the seeds (characterstics and "skills") indicating that sort of thing.
And as long as I am digressing, I have always been proud of my idea (probably not original but I did not hear of it elsewhere before I considered it) that the "Beast" in Revelations refers to a government gone bad just as much as the leader himself.
A beast devours food, makes lots of noise, stress, destruction, and overpowers any who get in its way. It lives to protect itself and wreak havoc at the expense of all else. The beast (especially at war) has no regard for law, love, human life, youth, innocence, civil rights, history, reason, tradition, culture, religion, morals, or consistency. The beast can be contradictory because it is vicarious (in other words things are "right" or "true" just because it says so). The beast is inherently corrupt and like a den of thieves, there is no honor within it.
Cheery, aren't I?
Have a good day!
I have trouble believing in personal appearances by gods and demons. That said, your idea unveils the proper, and most powerful, agent for evil on earth.
