The problem for the President (this is me, not the Washington Post folks) is there are a lot of people saying a lot of things on the GOP side of the equation: The Presidential candidates, Republicans in the House single point of reference is the President. In this case it happens to be Barack Obama, but if it were John McCain or Hillary Clinton the focus would be the same.
The Administration speaks with one voice - or at least it sings one tune. It is the tune called by the President of the United States and this one can blame his predecessor, the European Union, the Republicans on The Hill, or a rogue asteroid.
He's the president and the blame for lack of bucks in people's pockets stops with him.
The most damning line in the Washington Post analysis might well be "growing questions about the president's capacity to lead."
There's a reason the office carries the unofficial title of "Leader of the Free World." If voters don't think he's up to it, they will find someone who they think will be.
