Gowdy is a wing-nut, but given his background, I suspect he understands it perfectly well. His loud indignancy is for the cameras. The Justice Department exists to enforce the law. It doesn't exist to pursue the kind of politicized witch hunts DT and his enablers in Congress may demand. The only reason a special council would be appointed is if there is a good reason that a normal prosecutor couldn't. It's far better for an ordinary prosecutor to handle cases if at all possible. In this case, no actual crime has been articulated, and even if it were, there would be no reason that a regular career prosecutor couldn't handle the case.
It bears remembering that as long as it doesn't impact their work, a prosecutor's personal political opinions do not constitute a conflict of interest, as long as they do their job according to the law. I wonder if you think there's anyone who could possibly be neutral on the election.
You would think so ... however, we all know what this is really about. Trump and his band of misfits KNOW he is guilty and need to manufacture a reason to shut down the investigation.
