Does Trump ever go over the border? If you took his words literally, you would have no choice but to conclude that he is psychotic. A delusion is "a fixed false belief that is resistant to reason or confrontation with actual fact." Despite all evidence to the contrary, Trump asserts that he was tapped by Obama (apparently James Comey concluded Trump was "crazy" when Trump tweeted that) and had the biggest inauguration crowd size in history — classic persecutory and grandiose delusions.
