How can Democrats defuse inevitable Republican attacks on contemporary liberalism’s “unpopular stuff” — to use Klein’s phrase — much of which involves issues related to race and immigration along with the disputes raised by identity politics on the left?

Shor observes that “We’ve ended up in a situation where white liberals are more left wing than Black and Hispanic Democrats on pretty much every issue: taxes, health care, policing, and even on racial issues or various measures of ‘racial resentment’, ” before adding, “So as white liberals increasingly define the party’s image and messaging, that’s going to turn off nonwhite conservative Democrats and push them against us.”

The result?

“The joke is that the G.O.P. is really assembling the multiracial working-class coalition that the left has always dreamed of,” Shor told Politico in an interview after the election in November.
