DETROIT, Michigan — “It’s a turning point for our nation.” That is how Amir Makled, a Dearborn lawyer who has made a career out of anti-Israel advocacy, described the ascent of his longtime pal Abdul El-Sayed, now the Democratic nominee for a Michigan U.S. Senate seat. At El-Sayed’s primary night party in downtown Detroit on Tuesday, Makled, 39, predicted the campaign’s progressive populism would reverberate far beyond the state. “This platform is resonating with folks from Colorado, New Jersey, New York,” he told me over the din of Motown oldies. He’s now one election away from a seat that could determine control of the U.S. Senate.
