His Hugo Chavez moment.
Exactly. The thuggish move of a Chicago thug dictator wannabe throwing his weight around, in a forum where the Supreme Court is helpless to defend itself (or so Obama thought!).
Notice also, he dissed the Congress itself, by saying he will issue executive order to bypass their refusal to set up deficit commission.
He's dissing Constitutional separation of powers, trying to consolidate power in executive branch (for himself).
