As Ivanka Trump said in her book, The Trump Card [check John Oliver's interpretation here], perception is more important than reality, her father, the president of the US, suffers from an acute syndrome of ego-maniacal narcissism. I could see why someone would vote for DJT and think he's doing a terrific, fantastic job in is first 100 days, simply because his fans loathed Obama and they're happy hated Hillary isn't in the White House.
But any reasonable person has to acknowledge Trump's lies, character flaws, bad temperament, lack of knowledge about important issues, his impulsiveness and lack of good judgement, his flooding the so-called swamp with more muck, and his nonresidential demeanor, etc. So anyone who still thinks Trump is fit to be president they have to argue that all these don't really matter. I just can't see how anyone can make this argument.
At any rate, here's a excerpt from a Rolling Stone article:
2. Is preoccupied with fantasies of unlimited success, power, brilliance, beauty or ideal love ("I alone can fix it"; "It's very hard for them to attack me on looks, because I'm so good-looking").
3. Believes that he or she is "special" and unique and can only be understood by, or should associate with, other special or high-status people or institutions ("Part of the beauty of me is that I'm very rich").
4. Requires excessive admiration ("They said it was the biggest standing ovation since Peyton Manning had won the Super Bowl").
5. Has a sense of entitlement ("When you're a star, they let you do it. You can do anything. Grab them by the pussy").
6. Is interpersonally exploitative (see above).
7. Lacks empathy, is unwilling to recognize or identify with the feelings and needs of others ("He's not a war hero . . . he was captured. I like people that weren't captured").
8. Is often envious of others or believes that others are envious of him or her ("I'm the president, and you're not").
9. Shows arrogant, haughty behaviors or attitudes ("I could stand in the middle of 5th Avenue and shoot somebody, and I wouldn't lose any voters").
