The problem is that the press is contributing to him achieving that goal by helping Trump spread his racist message/language/acts. He also does it to divert attention from his many legal problems:
Why is Donald Trump different from all other presidents? Because he deliberately divides the country for political gain. It’s his strategy for governing. He’s “The Great Divider.”
President Trump did not create the nation’s political division. It’s been growing for over 50 years. His predecessors — George H.W. Bush, Bill Clinton, George W. Bush, Barack Obama — all promised to heal the division. They all failed. Trump never pretended to be a healer. He saw the country’s division as a political opportunity he could exploit.
It worked for him in 2016. He expects it to work for him again in 2020. “I’m going to do it the same way I did it the first time,” Trump told ABC News. Not by broadening his support the way most incumbents do when they run for a second term. By hardening it.
