It sucks he lost his job for posting facts, but this time Trump's approval rating and polling has plummeted since the start of the crisis.
All he had to do was calm down tensions and pretend to unify the country. Instead he posted stuff like 'when the looting starts, the shooting starts' and blamed a 75 year protestor after he was pushed by police officers. Stuff like this impacts peoples opinions way more than random looters robbing Target stores. It doesn't affect loyal Trumpists, they will defend him even if tells them to eat shit and die, but swing voters are definitely affected. Besides, people's opinion on BLM has really gone up in the last 6 years.
