Voting rights expert Ari Berman has a remarkable piece in Mother Jones about how thoroughly and effectively the Democratic vote was suppressed in Wisconsin. There's lots more, go read the entire piece for the details:

On election night, [Andrea] 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.

Clinton’s stunning loss in Wisconsin was blamed on her failure to campaign in the state, and the depressed turnout was attributed to a lack of enthusiasm for either candidate. “Perhaps the biggest drags on voter turnout in Milwaukee, as in the rest of the country, were the candidates themselves,” Sabrina Tavernise of the New York Times wrote in a post-election dispatch that typified this line of analysis. “To some, it was like having to choose between broccoli and liver.”

The impact of Wisconsin’s voter ID law received almost no attention. When it did, it was often dismissive. Two days after the election, Talking Points Memo ran a piece by University of California-Irvine law professor Rick Hasen under the headline “Democrats Blame ‘Voter Suppression’ for Clinton Loss at Their Peril.” Wisconsin Gov. Scott Walker said it was “a load of crap” to claim that the voter ID law had led to lower turnout. When Clinton, in an interview with New York magazine, said her loss was “aided and abetted by the suppression of the vote, particularly in Wisconsin,” the Washington Examiner responded, “Hillary Clinton Blames Voter Suppression for Losing a State She Didn’t Visit Once During the Election.” As the months went on, pundits on the right and left turned Clinton’s loss into a case study for her campaign’s incompetence and the Democratic Party’s broader abandonment of the white working class. Voter suppression efforts were practically ignored, when they weren’t mocked.

Stories like Anthony’s went largely unreported. An analysis by Media Matters for America found that only 8.9 percent of TV news segments on voting rights from July 2016 to June 2017 “discussed the impact voter suppression laws had on the 2016 election,” while more than 70 percent “were about Trump’s false claims of voter fraud and noncitizen voting.” During the 2016 campaign, there were 25 presidential debates but not a single question about voter suppression. The media has spent countless hours interviewing Trump voters but almost no time reporting on disenfranchised voters like Anthony.

If we do not turn out for the midterms in record numbers, we will never be able to fix this -- and we can look forward to a permanent Republican "majority."
