When the election is over and should Trump be elected, Obama will quietly undermine confidence in the US Dollar to make it look like foreign countries are dumping the Dollar in response to Trump being the President Elect. No matter how much corporate likes Trump, we are globally entangled and they will have to adjust with the markets despite the election results.
Obama may also Withdraw Military Personnel allowing conditions to worsen as Trump approaches his inauguration. They will say the escalation of attacks and killing are a reaction to Trump being elected.
Look for the Justice Dept to release statements or file charges that would be a wedge issue between Trump and Hillary. Maybe a reversal of previous findings (new evidence) establishing a cause for reopening cases from the past 7 years. Imagine the outrage if charges were suddenly filed by the DOJ for the deaths of Trayvon Martin, Micheal Brown, Freddie Gray, etc. It's not impossible to expect the clash and drive this would send rippling through the electoral map.
There are many current issues that are highly visible and could easily be amplified to stir up public reaction. Healthcare, just to pick an obvious topic important to Obama.
But a DOJ investigation in voting results after the election and before Trump is sworn in, would be powerful. All they would have to do is warn the public that once Trump is sworn in he could halt any investigation and influence the findings to bury evidence of a stolen election. Obama's final con on his supporters could be to offer them Hope that Trump's election results could Change.
You’ve learned to think like Obama.
