I think that anyone with any discernment, via the Holy Spirit, can immediately tell Obama is under demonic possession or oppression as you pointed out - and his takeover by the demonic is getting more intense.
I read a story a few years back, I cannot remember the source. It related that during the 2008 speech for the DNC in Denver (where his worshipers voted him as a "god" in a Styrofoam temple), Obama had an "incident" back stage before the event.
His aides said he was in a panic, and they had to lay him down. His eyes started twitching, and they said it was like he was "in a trance." After a while, he woke up, and there was sheer confidence in his face again. He walked to the podium and gave his speech.
I believed that story, and I believe he is under demonic control.
Interesting story, I had never heard that before,
And to be clear, just because a fly lands on someones forehead, I wouldn’t immediately presume anything spiritual from it,
Jesus said the light of the body is in the eyes, and his eyes are very dark,
By “demonic control” you surely mean Valerie Jarret.
