Imo he’s a sociopath and pathological liar. Always has been. I think it came back to bite him on his earlier runs for President but times and media have changed. I think they needed a comforting old white guy to offset Obama and it worked and now he’s a terrible president who will probably win again because Trump is an ass who can’t keep his mouth shut and too many republicans are idiots who value ideology over practicality. Obviously it’s more complicated mess than this.
