The shadow government. The same one that attacked Joe the Plumber for making ZerO look bad during a debate even though "Joe" did not even attend.
The shadow government is liberal Democrats who put Party before country and seek to tear down their political opponents by any means necessary and using their unelected government jobs to thwart the elected administration and expose people even if such leaks are criminal (as in the case of those who spilled details of Joe's record).
He'd done nothing criminal. However, agents of the State of Ohio commited criminal acts against Joe(not his real name).
He will eventually be elected Congress. He will also be awarded millions of dollars in damages by Ohio and federal courts.
The agents who revealed confidential information were ordinary political appointees very typical of the sort Democrats ALWAYS appoint. They wouldn't have made it into the CIA as lightbulb changers.
