I'm gonna go w ‘really stupid’. It gives me no pleasure to say so, but this is an assessment based on my personal interactions w Obama’s hardcore fanbase. If they were smart enough to know the truth, AND to know the degree to which Obama is lying, there would be tiny indications here and there. Mostly it would be in the form or genuine, not snarky humor. The glimpses would be small and fleeting, but sufficient to let you know you're dealing w a smart person who gets, deep down inside, that they are covering for a relentless liar.
That never happens. The only ‘humor’ known to Obots runs along the lines of, ‘Birfers are stoopid—hahahahaha’. Iow, there is no humor and/or self awareness at all. Meaning, they really are too thick to realize how pathologically their hero lies.
Sad.
