Democrats are exercised about Russian hacking of the DNC emails and the impact that conceivably might have had on an election they definitely lost. Why now?
Where was their outrage when some hackers, likely Chinese or Russian, broke into the records of the Office of Personnel Management? Those vandals stole the private information of some 20 million present and former Federal employees. In charge of the Executive Branch at the time, a Democrat named Obama.
I believe the OPM hack was demonstrably orders of magnitude more serious than John Podesta's emails. Both made Democrats look inept, or criminally negligent in the OPM case, but only the unimportant one has caused much outcry.
The inevitable conclusion: Democrats only care about losing elections, not about malfeasance in office.
