Walz hit Trump for not being in touch with everyday people, particularly autoworkers, following comments that Trump made in mid-October.

“The only thing he knows to how to manufacture is bulls***, and he’s continued to do it,” Walz said during a campaign stop in Detroit on Friday afternoon.

Trump said foreign automakers were “getting away with murder” by manufacturing the parts overseas and then assembling them in the United States.

“[U.S. autoworkers] don’t build cars. They take them out of a box, and they assemble them. We could have our child do it,” Trump said.

Walz said Trump “couldn’t open the damn door to a garbage truck, let alone” put a car together, a reference to Trump’s surprise appearance in a garbage truck press conference earlier this week after President Joe Biden called Trump supporters “garbage.”

“The Donald, who, by the way, got in that garbage truck wearing French cuffs with cuff links — no one I know wears those things to begin with but trying to tell us he’s a regular guy,” Walz said.

Trump is also campaigning in Michigan on Friday, offering a hard pitch to blue-collar and union workers in Warren, Michigan. While the leadership of the United Auto Workers union endorsed Harris, other prominent unions have declined to back her, including the Teamsters, giving Trump an opening.

Walz visited the Michigan town of Flint, the birthplace of General Motors, later on Friday afternoon and hit on the same points that Trump was incapable of reviving the Michigan economy and that it was time to turn the page on the embattled Republican to a new, more hopeful chapter in U.S. history.

Walz said voters who believed the economy was better during Trump’s presidency from 2017 to 2021 were mistaken and that the country was worse off when he left office than when he entered.

“Donald Trump botched the pandemic response so poorly. Not only did we lose 10 million jobs, we were pitted into a hunger game against our neighbors to find toilet paper. That’s how bad it was,” Walz said in Detroit.

A RealClearPolitics average of polling in Michigan conducted between Oct. 17 and Oct. 30 found Harris ahead just slightly: 48.3% to 47.5%.
