Since libs suffer from a destructive mental disease that brings on total insanity such that they cannot comprehend reality from fantasy. Everything that they “see” that is actually normal is abnormal; IE: right is wrong, male is female, up is down, good is bad, etc. etc.etc. So to have one of these insane morons call POTUS insane means that he’s as sane as any of the rest of us.
BTW, this clown has those same insane lib eyes as Cuomo, Shifty and a few others. He ain’t “hittin’ on all four cylinders” and is definitely not the sharpest tool in the shed.
25 years ago, Michelle Malkin described this very issue in her book Unhinged: Exposing Liberals Gone Wild. I don't think she could imagine that book underestimated how "unhinged" the Left can be.
