PITTSBURGH — Minnesota Gov. Tim Walz urged a crowd of Pittsburgh Steelers fans to vote early as he rallied a few hundred of them Tuesday night at the professional football team’s home at Acrisure Stadium.

Vice President Kamala Harris’ Democratic presidential running mate campaigned in the southwestern Pennsylvania city as the campaign continues its blitz of the coveted swing state that could decide the 2024 presidential contest.

The race between Harris and former President Donald Trump, the Republican presidential nominee, remains razor-thin in the Keystone State.

Former Steeler Will Allen introduced Walz to a cheering crowd dotted with Steelers hats, jerseys and Terrible Towels, the team’s official rally towel.

“Give me my moment here, yesterday I made my first trip to Lambeau Field,” Walz said, referring to his trip to Green Bay, Wisconsin, and the home of the Green Bay Packers football team. “Today, I’m making my first trip into Steeler territory, so thank you.”

The former high school football coach and teacher visited Wisconsin Monday, which is alongside Pennsylvania on the list of must-win swing states. The others include Arizona, Georgia, Michigan, Nevada and North Carolina.

Early mail-in ballot voting is already underway in Pennsylvania.

“If you’re voting by mail, get the damn thing in the mail as soon as possible,” Walz said.

Harris campaigned in Erie, Pennsylvania, Monday night before heading to Michigan Tuesday.

Attacks on Trump

Like Harris did in the state’s northwestern corner the previous night, Walz roused the Pittsburgh crowd by attacking Trump’s mental fitness.

“I would not usually encourage this, but go watch this guy, watch his town hall. He stopped taking questions and stood frozen on stage for 30 minutes while they played his Spotify list,” Walz said, referring to Trump’s Monday night town hall outside of Philadelphia.

“If this were your grandfather, you would take the keys away,” Walz said to laughter. “And I tell you this, look, it would be funny if this guy weren’t running for president of the United States.”

In Erie, Harris warned that Trump is “unhinged” and played video clips of the former president explaining his potential plans to use the military to silence “the enemy from within.”

Trump wrote on his social media platform Tuesday morning that Harris’ own health report is “really bad.”

“With all of the problems that she has, there is a real question as to whether or not she should be running for President!” he wrote on Truth Social.

Harris’ medical report released Saturday describes her “in excellent health.”

Walz on the farm

While Walz wore a white shirt and sports jacket when talking to the football fans, earlier in the day he donned a flannel shirt and told supporters gathered outside a barn in Lawrence County that he and Harris would fight for American farmers and resources for rural residents.

The governor also highlighted his bona fides as a veteran, hunter and gun owner. His speech can be viewed in full on C-SPAN.

The Harris-Walz campaign released a plan Tuesday for rural America that promised to shore up rural health care and support small farms.

Walz also stopped at a garden center and cafe in Butler County before heading into the city.

The pro-Democrat Rural USA political action committee highlighted economic analyses Tuesday that show Trump’s promised tariffs would cause farmers to lose business as exports would decline.

Pennsylvania farmers could lose $111 million in soy exports, $50 million in corn exports, $22 million in beef exports and $20 million in wheat exports, according to the analysis from the University of Illinois Department of Agriculture and Consumer Economics.

“These new studies literally show that Trump’s tariffs will put Pennsylvania farmers out of business,” Chris Gibbs, an Ohio corn and soybean farmer and president of Rural Voices USA, said in a statement Tuesday. “Exports are vital for Pennsylvania farmers and they cannot absorb the sharp fall in exports and prices these studies foreshadow.”

Trump defended his tariff proposals at the Economic Club of Chicago earlier Tuesday.? He told Bloomberg Editor-in-Chief John Micklethwait during an hour-long interview that he would spur a manufacturing boom in the U.S. by making tariffs “so high, so horrible, so obnoxious” that companies would relocate.

Republican vice presidential nominee Sen. J.D. Vance of Ohio is scheduled to campaign in Pittsburgh Thursday.
