Michigan’s Senate race has become a battle over Democratic nominee Abdul El-Sayed. Republicans have spent tens of millions of dollars to portray him as a dangerous radical, as El-Sayed responds by traveling across Michigan, meeting voters, and focusing on health care and the cost of living. But the progressive candidate has also embraced confrontation with President Donald Trump and Republican opponent Mike Rogers. His campaign has drawn national attention, with prominent Democrats rallying behind him and outside groups spending heavily against him. Both sides see the race as a test of their politics, with implications far beyond Michigan.
