Michigan is a battleground state, in every sense of the word. Here, purple doesn't mean moderate; it means the 50-50, Red/Blue split is a chasm. On a recent Saturday in Traverse City, Mich., people gathered half of them Red, the other half Blue " brought together by Braver Angels, a not-for-profit attempting to narrow the divide. "I'm here out of concern for our country, and our democracy," said one attendee, Jane. Started in 2016, Braver Angels now holds sessions nationwide. It was shaped by Bill Doherty, who teaches relationships at the University of Minnesota. He's also a marriage counselor. Correspondent Martha Teichner asked Doherty, "Is it a proper analogy: Reds and Blues in America, and couples on the brink of divorce?" "There is an analogy to couples on the brink," Doherty replied. "A big difference is that divorce is not possible in America." In Traverse City, participants arrived uneasy at first, defensive. Task #1 at a Red/Blue workshop: stereotypes. Reds and Blues, seated in separate rooms, are asked to list what "they" call "you." Facilitators then ask each side if there's is a kernel of truth in those stereotypes. Tim said, "The passion for the pro-life cause sometimes seems not to hear women." And so it goes, for three hours, peeling back the onion of opinion, looking for common ground. No trying to change anybody's mind. Divided they were, but they showed up, because they wanted to know each other not by label, but by name. Braver Angels has held more than 2,000 workshops and is growing.
