I’ll buy that. I was thinking that he also had so much on his plate that focusing on one part of it was all he could handle. Remember, Issa is also investigating Solyndra and the other “green” company scams and I don’t know how many other things. F&F is only one of several investigations he’s got going.
I think that Issa is incredibly smart. He knows that political investigations and censure votes can be just as damaging to Republicans as to the Democrats, but an actual criminal investigation changes the dynamics.
It doesn’t quite work the same for the Democrats because of the media complicity.
