The battleground state of Wisconsin hosted Democratic Presidential nominee and current Vice President Kamala Harris and her Vice President pick, Minnesota Gov. Tim Walz in Eau Claire on Wednesday, on the same day – and city – as Republican Vice-Presidential candidate JD Vance’s rally.

This comes a day after Harris and Walz took the stage together in Philadelphia.

5 EYEWITNESS NEWS caught up with some supporters who were trying to make it to the rally and the impact the event had.

“It means Wisconsin is a significant place… in the entire United States to help decide the entire future of the United States election and the future of our country,” said Catherine Emmanuelle. “I’ve never seen this many cars in Eau Claire… we don’t have traffic in Eau Claire.”

“It’s insane, it shows how excited everybody is for this, I mean it’s a huge turnout for something for Eau Claire. I’ve heard people on Twitter have been out for like a mile-and-a-half outside of Eau Claire so it’s exciting,” said Casey Yonash.

A key message the two shared at the rally was about a brighter future with affordable housing, child care and health care. The two candidates also brought up a similar message about not moving the country backwards with Republicans but instead moving forward with their ticket.

“It was invigorating, really charged things up, I was glad we came. It made Wisconsin really special,” said supporter Denise after the rally.

Meanwhile, Vance, the running mate of former president Donald Trump, spoke at Wollard International, a manufacturing facility in Eau Claire. Vance took on Harris and Walz during his own rally in Philadelphia on Tuesday night.

“I think what Tim Walz’s selection says is Kamala Harris has bent the knee to the far left of her party,” said Vance.

Walz has previously said he’s up for a Vice-Presidential debate with Vance.

Trump’s campaign is criticizing Harris’ choice of Walz, saying in a statement, “From opposing his own carbon-free agenda, to suggesting stricter emission standards for gas-powered cars, and embracing policies to allow convicted felons to vote, Walz is obsessed with spreading California’s dangerously liberal agenda far and wide.”

Four years ago, Wisconsin was a state where the election results were heavily contested, and on Wednesday, Harris and Walz are hoping to energize voters. However, this is also an important time for the Harris camp to introduce Walz to the world.

Political experts point out that will mean opening himself up for immense scrutiny on the national level, as his policies and decisions on things like the COVID-19 crisis, as well as his response to the George Floyd riots, will now go under the microscope.

Experts also say that Walz will likely emphasize his background as a teacher, football coach, his more than two decades with the National Guard, his upbringing in Nebraska and his experience as a Minnesota Congressmember and Governor.

“Certainly, he balances Vice President Harris’ strengths and weaknesses. Very different backgrounds, parts of the country, demographics – so even though they’re the same age, they’ve lived very different lives that led up to their lives in public service,” said Kathryn Pearson, an associate political science professor at the University of Minnesota.
