Rep. Debbie Dingell (D-MI) joins Andrea Mitchell to discuss how the race is shaping up in Michigan and her warning to Democrats to pay attention to Michigan union members. “I did say for the first time yesterday, I think the momentum is on Biden’s side-women who stayed home, that didn’t think their vote mattered, are coming out in record numbers.”
