The Michigan primary was settled on Tuesday, but some mainstream media are still chattering over Dearborn – a city said to be 30-40 percent Arab, yet voted decisively for the lone Jewish candidate, Bernie Sanders.

And so many are still crowing about how so very wrong the pundits were to fret over anti-Semitism, it's hard to find the fretting. The stories are almost all "Nyah, nyah, we knew it all along."

The International Business Times let out some of the loudest chortles:

As the results rolled in, television pundits like Lawrence O’Donnell and Chuck Todd marveled on MSNBC that Sanders was doing so well in Dearborn “despite” the large Arab-American population there. WNYC radio host Brian Lehrer tweeted that Sanders’ dominance in Dearborn was “the stat of the night,” later adding “It’s official: Arab city feels the Jewish Bern.” Meanwhile, The Week dubbed it “just one more strange data point in an election overflowing with them.”

The assumption implicit in such commentary, of course, is that Muslims are biased against Jews — and that when they do cast a vote for Jewish candidates, it’s because they’ve somehow managed to overcome their own inherent anti-Semitism. But this fascination with Dearborn’s support of Sanders actually demonstrates the media industry’s own all-too-prevalent prejudice — and reveals how much reporting on American Muslims is still rooted in an unsophisticated naiveté about what motivates them.

The article quotes a prof saying that “the ‘Muslims voting for a Jew’ tagline is trite." And it quotes a Libyan-American writer saying that mainstream media are "guilty of promoting two-dimensional caricatures of Muslims and Arabs."

IBTimes isn’t the only miscreant, of course. The Huffington Post began its stridence yesterday with the headline: "Yes, Muslims Voted for A Jewish Candidate. Pundits Shouldn't Be Surprised." Added the subhead: "Arab-Americans in Dearborn, Michigan, shut down uneducated commentary about their support for Bernie Sanders."
