Unfortunately, he doesn't realize it, or accept it. And, he has plans, big plans, to continue his fundamental transformation of America. Years ago he established his own non-profit PAC, called Organizing For Action(OFA) https://en.wikipedia.org/wiki/Organizing_for_Action as a shell to finance his intent to take community organizing national.
In reality, he intends to use it as the basis for a shadow government to undermine Trump and his agenda, and advance the progressive cause. http://www.thegatewaypundit.com/2016/12/report-obama-setting-shadow-government-undermine-trump-starting-inauguration-day/
Time will tell if he's successful (I think he's in for a rude awakening), but he will cause a lot of trouble, and the media will support him in every way possible.
The Chcago thugocracy has copied everything that the clintoons ever did. Right down to the Clinton Crime family Foundation.
So El Zero of course has his own crime syndicate foundation.
He will still do what he has learned to do fund raise money. It's all he knows. what he actually does with the dough remains to be seen.
As far as a shadow govt. goes we have had that for many years. It already exists. Chance are good el Zero is a card carrying member who would like to move up from a buck private status to Master Sergeant.
