Respectfully, it does little or no good for congress to “investigate” all the impeachable offenses (or lack of constitutional qualification for office) if it remains obvious that the congressional leadership either supports O or at least is determined to continue proteting him
and... he is not dumb. he can see that there is no danger whatsoever from congress/comrade Boehner
Hillary and Petraeus both announced their resignations in the morning hours the day after the fraudulent election of 2012. Nobody expected odinga to win, not even odinga himself, and all the participants in the Benghazi cover-up had obviously been promised presidential pardons to be delivered prior to his expected departure from office in January 2013.
When the fraud machine cranked out the miracle, a whole truckload of criminal Democrats experienced panic beyond compare. "OMG, there goes my presidential pardon!"
With four more years, and plenty of time for impeachment proceedings, there was nothing left to do but keep cranking out daily crises of treason, bribery, high crimes and misdemeanors.
Impeachment is a House process. Whether the Senate convicts, or ever would convict, or ever even pretend to try any such impeachment, the Constitutional suspension of the presidential power of pardon is triggered by the impeachment process, and possibly retroactive to the beginnings of investigations for impeachable offenses. There are many.
