If one closely studies the personalities of Hitler (and I have) and Trump for many years, it would seem obvious that the only major difference between the two is the effect that money has had on Trump’s path to power contrasted to that of the once penniless Hitler’s takeover of Germany.
As far as accusing Obama of being a Hitler that could not be farther from the truth. Obama is a thoughtful caring personality of the highest character, whereas Hitler and Trump are both ruthless megalomaniacs who prey upon the worst human impulses for personal gain and glory, a needy wall they feel driven to build against their own deep down self-loathing.
