Tons more than Donald PET Trump does even. Obama is a ware of this. I read in the news that he distinctly said he was going to move out of the White House but stay close to the process and monitor and help that way. He said he cannot do anything negative at this juncture and must wait until he is no longer President.
I think that means he will be more vocal in the media and try and organize and thwart Trump from without. He, Bernie, Hillary, have a lot more behind them than merely Bernie. And Bernie had a lot of power. There are intelligent people on the Blue ticket. There are clever and highly reactive people on the Red side. We can overcome.
Of course he does. But I applaud him for using great restraint in public. The guy coming in to replace him may want to take some notes on how that is done.
