Can Democrats diminish the bigotry that Donald Trump has unleashed in this country?

Stung by the success of Trump’s anti-immigrant, racist campaign themes in 2016, left-of-center advocacy groups — think tanks, unions, progressive academics and Democratic consultants — are developing tools this year to counter the continuing Republican assault on liberal values, based on the optimistic assumption that the reservoir of white animosity is not so deep that Trump is assured re-election.

These efforts on the left challenge the long history of Republican success in exploiting race and a host of ancillary issues — crime, welfare, social disorder, family breakdown, homelessness — a history that includes Richard Nixon in 1968 and 1972, Ronald Reagan in 1980, George H.W. Bush in 1988 and Donald Trump in 2016.

That history points to the relentless power of racial resentment in American politics. Despite polling that shows greater acceptance of racial equality, this issue is as potent a source of political strength for Trump today as it was for Nixon a half century ago. CONT.
