Here's a start:
Maybe--just maybe--one or two of those "investments" of tax money will pay off. We already know that several have not; that they became "Oooooopsies".
Am I able to calculate exactly what those "Oooooopsies" cost me, personally?
But that's the red herring of the (D)/Obozo apologists. They cannot allow discussion of the real issue: Gummint crony-capitalism, corruption, and fraud.
