Clubbing Obama's Seals

What is with Obama and these damned seals? First, before he even received his party's nomination, he rolls out his own variation on the standard presidential seal. Then, he makes up an office and creates a seal for it. He was a U.S. Senator, the presidential nominee of a major political party, and in a few weeks he's going to be the president of the United States of America for crying out loud. Does he really need to aggrandize himself with this crap?
