I really think of Obama government as populism (disclaimer: I live in another country with a lot of populism). The IRS scandal is part of that. He plays nice cards in public but in secret he has another agenda. At one point you connect the dots when he plays the same tricks.
From what I've seen, Obama is pretty peeved about the IRS thing. Mainly because it spent a lot of political capital he needed for other projects... like this one.
