I came up with this partial list of repugnant personality traits some years ago. While no single trait identifies a repugnant the more the merrier. There have been a number of times where I've told a repugnant, not asked, they voted for McCain, Romney or are Trump supporters, or Carson, or Cruz or whoever, by identifying them with these traits. They always asked me how I knew, I respond with "goes with the personality".
Con Personality Traits
simple/narrow minded (punk)
childish/immature
gullible
petty
racist
self important/arrogant
hypocritical
distractive
delusional
excuse oriented
selfish
conspiratorially paranoiac
Think I'm kidding? Ask anybody you know displaying these characteristics, especially selfish and arrogant, who they voted for or will vote for and the vast majority will say Romney, McCain, Trump, Cruz, Carson, etc. I've done it many times with people I know and I haven't missed yet.
Deal with it!
Now let's here the childish, insulting distractions . . .
Any questions?
