Not all investments are winners.
Solyndra is just a made up controversy for election purposes. After the election everyone will forget about it. The loan program that Solyndra's loan was a part of budgeted for a 12% or 13% loss rate. With Solyndra and the 2 other failures I'm aware of the loss rate of the program is still under 5%. The loan program was designed to be somewhat like a venture capital fund. You don't expect all of your investments to work out. I'd also like to point out that the Solyndra loan application was started under the Bush administration and they pushed pretty hard to get it done before they left office but couldn't get it done.
