Bringing in these right wing media people from Breitbart is symptomatic of Trump's horrible decision-making. He loved poking at those issues about race and bigotry in the primary, because he got plenty of support from the base for that, and it was successful. He was being lauded for his ability to connect with the lowest common denominator amongst the GOP base -- racial resentments.
But in the general, he is getting killed for those same tactics, and he cannot understand how this has turned against him. He is being criticized, which he cannot stand. And so he is restoring to yet another echo chamber around him, telling him how great he is, and how right he is.
These yahoos he has hired are not going to help him. They are just going to cause him to dig himself into a deeper hole with anyone other than the GOP racial divide base. Yuge mistake, imo.
