For all of Obama’s talk of the new politics, there’s one very old political dodge he’s rather fond of: blaming the staff. ABC’s Jack Tapper counts up 14 incidents in which Obama has claimed that some problem was caused not by him but by a staff member; Obama is particularly fond of this line when things show up suggesting that he’s shifted his political positions towards the centre now that he’s running for national office. At some point before this is over, this excuse is going to wear rather thin.
