Worst nightmare would be explicit exposure of collusion between the DNC, the Obama administration, and unelected offices like the IRS and Homeland Security to manipulate the 2012 election.
Yeah, we'd all be crying a river if the truth got out... Oh, you left off the FBI - I think they were in on the crime of targeting American citizens BECAUSE they were political opponents of Obama...
Again -- we're defining "worst nightmare."
The "worst nightmare" is the collusion and collaboration of BOTH parties having already committed treason and amidst current bloody plans to replace the US Constitution with a "World Constitution".
US sovereignty would then be eliminated and folded into one more nation comprising a "United Nations" with subservience to the supreme authority of a One World Government.
