Trump has always talked about "America" as a collective in terms of wanting to win on trade deals and the economy. But he has also always singled out Democrats in a way that communicates that he doesn't view serving them as part of his job. No president ever really tries to serve both agendas, but Trump doesn't even pretend. He's openly disdainful.
He could be less antagonistic, but the left and m.s.m. could also be more objective. Neither seems willing to do it first.
