Barack Obama is a cypher in many ways. He doesn't have much of a record, and what record there is indicates that he is pretty much a far left liberal and a socialist, probably of the fascist variety. His friends are a scary group that includes back racists and terrorists. Samantha Power is one of his foreign policy advisers. She is part of the "Blame America First" crowd. Here is a discussion of her views on foreign policy. (Basically she is for a lot of talk and no action, not even to defend America. She is Irish, so maybe that makes sense.)
