No Info On Stimulus Effect – Why Not?

Why has the Obama admin been silent on the effects of the stimulus? The public thinks that a trillion dollars has been spent with no effect. HAS there been an effect?
The Obama administration should be showing where jobs are being saved by stimulus money showing up. They should be hiliting where construction is beginning. They should be taking credit for any good news that shows up. So far, if they have been doing this I certainly haven’t heard it, and I know the general public hasn’t either.
This is bound to be hurting public perception of government and of Obama.
