Rigged: How Voter Suppression Threw Wisconsin to Trump
I shortened ny snippet for brevity.

"On election night, Anthony was shocked to see Trump carry Wisconsin by nearly 23,000 votes. The state, which ranked second in the nation in voter participation in 2008 and 2012, saw its lowest turnout since 2000. More than half the state’s decline in turnout occurred in Milwaukee, which Clinton carried by a 77-18 margin, but where almost 41,000 fewer people voted in 2016 than in 2012. Turnout fell only slightly in white middle-class areas of the city but plunged in black ones. In Anthony’s old district, where aging houses on quiet tree-lined streets are interspersed with boarded-up buildings and vacant lots, turnout dropped by 23 percent from 2012. This is where Clinton lost the state and, with it, the larger narrative about the election."

So, i'm not blaming anyone factor for tge loss but there are many. The Sanders tRump voters were in the noise in a traditional dem stronghold.
