Michael Finnegan (LA Times) provides the evidence for Scope of Trump's lies are unprecedented for a modern presidential candidate, and then concludes this way.
Marty Kaplan, a professor of entertainment, media and society at the University of Southern California's Annenberg School for Communication and Journalism, has two theories on Trump's lies.
Perhaps he's just putting on an act, like P.T. Barnum -- a "marketer, con, snake-oil salesman who knows better, knows how to get the rubes into the tent." Or maybe, Kaplan suggested, Trump is just "completely unconstrained by logic, rules, tradition, truth, law."
"I'm confused," he said, "whether the whole fact-free zone that he's in is a strategic calculation or a kind of psychosis."
Translation: Trump is a calculating premeditating liar or just plain nuts, that is, totally delusional. Either way, it is frightening that so many Americans are willing to give Trump a pass on honesty. See Finnegan's article for examples from interviews with Trump supporters.
