A minor Republican primary battle in metro Detroit, Michigan, has exploded into the national consciousness after a white candidate called her Asian challenger a “ching-chong” and belittled her supporters as immigrants who didn’t belong in this country, raising serious questions about the re-emergence of racism, anti-immigrant sentiment and the dark underbelly of ethnic animosity in the era of Trump.

Wait, wait, did I say Republican? Sorry about that one; what I actually meant to say was Democrat.
