The odds of Donald Trump prevailing over Hillary Clinton in the November election stand at 98 percent, "Dilbert" creator Scott Adams insisted in a Tuesday column, because of Clinton's ongoing efforts to turn Americans against each other.

"Team Clinton has succeeded in perpetuating one of the greatest evils I have seen in my lifetime. Her side has branded Trump supporters (40 percent of voters) as Nazis, sexists, homophobes, racists, and a few other fighting words," wrote Adams, who had endorsed Clinton before switching to Trump in September.

"Their argument is built on confirmation bias and persuasion … Clinton's framing of Trump provides moral cover for any bullying behavior online or in person. No one can be a bad person for opposing Hitler, right?" Adams wrote. "I realize Trump supporters say bad things about Clinton supporters too. I don't defend the bad apples on either side. I'll just point out that Trump's message is about uniting all Americans under one flag."

"The Clinton message is that some Americans are good people and the other 40 percent are some form of deplorables, deserving of shame, vandalism, punishing taxation, and violence. She has literally turned Americans on each other. It is hard for me to imagine a worse thing for a presidential candidate to do," he added.

"As I often say, I don't know who has the best policies… But I do have a bad reaction to bullies. And I've reached my limit. Therefore … I endorse Donald Trump for President of the United States because I oppose bullying in all its forms," said Adams.

"The bullies are welcome to drown in their own bile while those of us who want a better world do what we've been doing for hundreds of years: Work to make it better while others complain about how we're doing it," he said. "Today I put Trump's odds of winning in a landslide back to 98 percent."

"Remember, I told you a few weeks ago that Trump couldn't win unless 'something changed.' Something just changed," Adams added.

Adams was saying as far back as June that Trump would win.
