Author on Hannity reviewed the facts and it does explain a lot.
Obama admin had been illegally surveilling opposition campaign as well as private citizens. ( Even despite a court order in 2011, they did not stop private citizen surveillance - including senators such as Rand Paul).
They never, ever expected Trump to win, but when he did, they realized that he would gain access to this information, and that he would make it public which would reflect very badly on Obama and his legacy (Nixon's admin was the last to illegally surveille the opposing campaign), and also would possibly result in jail time for minions like Susan Rice.
Thus, they needed a narrative that explained their actions. Hence the creation of the "Russian/Trump Conspiracy". They already knew that there was a fruitless search for such a connection by the FBI, and they felt this would provide the perfect excuse to explain why they had been surveilling people ("for the nation's best interest against intrusion of Russia, and "incidental surveillance").
The media was more than glad to oblige given their Frank-like hatred of Trump.
But now, the truth is starting to come out. There was no collusion, and they knew it.
I am reminded of Rachel Maddow asking insistently to some Obama admin guest, "what is our doomsday plan?" This was it.
This explains much, but as more facts come out, the focus is inevitably turning toward Obama and his admin.
Worst president EVER.
