I don't get this.

Trump did a pretty good delegitimizing himself years ago, and continued to do so once elected by a minority. Trump himself had no desire to unite anyone, let alone people who voted against him. Also, given his consistent ass clown behavior and incompetence its a bit rich (to put it kindly) to blame Democrats for what happened to him. And let's not discuss the grifting eh?

If you want to blame someone for "America not coming together" , blame Newt Gingrich.
