On Labor Day — designated a federal holiday in 1894 to honor America’s labor movement — at least eight Democratic candidates will hold rallies in five Midwest cities to tell workers just how far the country has veered from its pro-labor roots.

In Wisconsin, Gov. Scott Walker (R) has helped turn the state red by decimating public-sector unions. In Iowa, Republicans rolled back an increase in the minimum wage in March. Just last week, Illinois’ Republican governor vetoed a bill that would have raised the minimum wage. And Republican governors in Michigan andOhio have also pushed for regulations that would cripple workers.

In 2018, each will face challenges from unconventional, labor-aligned candidates inspired to run by President Trump’s election and the decline of pro-worker lawmakers, which has resulted in a political system in the Rust Belt that favors the wealthy over the working class. Each candidate will center their campaigns on their support for a $15 minimum wage, progressive health care, and pro-union policies.

Cathy Glasson, a registered nurse and union leader in Iowa who will officially announce after Labor Day her campaign for governor in 2018, said that before this year, she had never considered running for elected office.

“This wasn’t in my plan, but as a union leader, you take action when you see the problems ahead and you don’t sit back and wait for things to change,” she told ThinkProgress. “That’s why I decided when I saw what happened with the legislature and the rollback of the minimum wage. We had raised the minimum wage in five counties in Iowa and this administration literally took money out of the pockets of Iowans — 85,000 Iowans were affected by the rollback here.”

Like other first-time politicians throwing themselves into 2018, Glasson has been a union member for decades and will prioritize the need for more American workers to join unions and employee associations.

“The number one job of any elected official, particularly the governor, should be to raise wages and improve the standard living for all Iowans,” she said. “The union movement and the Fight for $15 and its allies realize that low pay is not okay.”

Glasson’s campaign will have the backing of her union, the Service Employees International Union (SEIU). One of the country’s largest labor unions, SEIU and its Fight for $15 arm — a national campaign to raise the minimum wage to $15 — will announce Monday a push to elect labor-friendly candidates in 2018 in the Midwest states where unions once held tremendous power. The union will budget roughly $100 million for the 2018 midterm elections — around $30 million more than it spent in 2016 — to flip the once-Democratic states back to blue.

In Milwaukee, Wisconsin, Mahlon Mitchell, the president of the Professional Fire Fighters Association of Wisconsin who announced his run for governor in July, will rally with workers at a hospital. In Cleveland, Ohio, talk show host and former Cincinnati Mayor Jerry Springer, who is considering a run for governor next year, will join workers at a march. In Des Moines, Iowa, Glasson will also rally at a medical center. In Chicago, Daniel Biss, Chris Kennedy and J.B. Pritzker, three leading 2018 Democratic gubernatorial candidates, will rally with SEIU’s president. And in Detroit, Michigan, Gretchen Whitmer, another gubernatorial candidate, will also rally at a hospital.

“With the election of Donald Trump, we’re seeing a wave of first-time candidates excited about creating change in each of our states,” Glasson said. “We need to give people something to go to the polls and stand in line and vote for.”

Randy Bryce, a Wisconsin ironworker known as “Iron Stache” who launched a challenge to House Speaker Paul Ryan (R-WI) in June and saw his campaign videogo viral, will also be participating in Labor Day events across Wisconsin. He told ThinkProgress that, other than his son’s birthday, Labor Day is his favorite holiday.

“Especially in Wisconsin, with all the blatant political attacks, it’s great to see people still getting together and the numbers seem to increase every year, instead of what they’re trying to do, which is decrease our membership,” he said. “It’s great seeing more people get angry, frustrated, and want to fight back at the attacks because the government isn’t doing anything to stand up for workers’ rights.”

In Wisconsin in particular, the labor movement has struggled to fight back against the “banana republicans” in office, as Bryce calls them. “The labor movement took everything that we had for granted up until Scott Walker got elected,” he said.

Republicans in Wisconsin have gerrymandered the state so they do not fear losing their seats, Bryce noted, but the union movement is going to latch onto policies that he believes will resonate with voters across party lines, like wages and health care.

The locations of Monday’s SEIU events — at hospitals and medical centers — is intentional. Labor Day will mark the first time hospital workers have joined the Fight for $15 and will represent a core group of workers involved in the effort to elect candidates who support not only keeping the Affordable Care Act but pushing for universal, single-payer health care.

Glasson, a registered nurse, said she knows Iowa can lead by example when it comes to Medicare for all.

“Iowans and Americans in general are just tired of not fixing the problem, and states like Iowa should lead on this,” she said. “We can do that because it’s a reasonable size states, we can figure out how to pay for it, we can put policies in place that can move that agenda.”

Bryce agreed. “It’s the right thing to do but it’s also going to help create jobs,” he said.

SEUI’s campaign will include a voter engagement drive aimed at expanding the turnout on Election Day in 2018. According to the New York Times, the union conducted a pilot project during the 2016 campaign in which it canvassed voters in two largely African-American neighborhoods of Detroit to spread information about which candidates support workers and higher wages.

“Over all, about 62 percent of voters the union talked to during the pilot project cast ballots in the presidential election, versus turnout of about 38 percent of voters who it did not talk to, according to data provided by the union,” the report noted. “Applying the same percentage to all of Detroit’s voters would have produced about 40,000 more total votes in 2016, an amount that would have almost certainly secured the state for [Hillary] Clinton.”

While the need to push out anti-worker Republicans in the Midwest is paramount, many of the labor-aligned Democrats are also running to provide a counter to the Trump administration. As Glasson noted, the administration has been a disaster for working families and has alienated labor more and more as the year progresses. In August, in the wake of the president’s comments about Charlottesville, AFL-CIO President Richard Trumka left the president’s manufacturing council, saying that some White House aides “turned out to be racist.”

Glasson said that because of the administration’s hostility toward labor, its critical to have pro-union individuals get involved in politics.

“Unions have been the only way that workers who drive our economy have a voice in politics,” Glasson said. “By collecting and pooling union members’ money, we are a force to be reckoned with in politics, and so the intentional attack on unions in the state of Iowa and the Midwest and beyond is intentional to silent the voice of everyday workers that need to have a voice in politics.”

Bryce agreed that if unions do not get involved now, the Trump administration could decimate the labor movement to a point of no return.

“You’re seeing a lot of people step up since this past election and see that if we don’t get our stuff together, what little we have left, it’s going to be totally gone.”
