After three years of Mr. Trump as president, 65 percent of black people say it is a “bad time” to be black in America, according to a January Washington Post-Ipsos poll. Just as dispiriting, most black people now say white Americans “do not understand” the discrimination they face. That applies to white Democrats as well as white Republicans…

And then there is the anxiety over the prospect of four more years of being invisible as the president sets national goals. For example, Mr. Trump regularly demeans government workers, many of whom are black. He’s still trying to dismantle the Affordable Care Act and cut financial aid to the unemployed…

Black Americans have had enough. They have an explosive, personal investment in defeating Mr. Trump in 2020. More than 80 percent of them say Mr. Trump is a racist. For them, defeating him is the civil rights movement of 2020.

And it is not an empty threat.

If black voters returned to the polls at their 2012 levels, the Democratic presidential candidate “would win the Electoral College by 294-244,” according to an analysis by the Center for American Progress.
