Live election updates: 80 million have voted early as Trump, Harris sprint to finish

Tim Walz called on voters in battleground Wisconsin to vote for an "optimistic" future during a rally in La Crosse.

"This election could be won, quite literally, through the state of Wisconsin, and it could be won right here through La Crosse," Harris' running mate said. "That's how close this thing could be. So we're taking nothing for granted."

Walz addressed policies he and Harris will focus on, including working to lower the cost of living for middle class Americans, addressing price gouging on groceries and making reproductive rights enshrined into law.

He said they have an opportunity to vote for "a future that either goes backwards -- is divisive, dark and angry -- or one that is hopeful, unified, inclusive."

"Swifties for Kamala," the grassroots organization of Taylor Swift fans working to elect former Vice President Kamala Harris, announced over the weekend they had sent over 250,000 mailers to Pennsylvania voters encouraging them to pledge their support to Harris, make a voting plan and encourage their friends to do the same.

Included in 50,000 of the mailers were friendship bracelets beaded with the words "voting era," a reference to the bracelets fans trade at Swift's Eras Tour.

"Every vote in this election matters, especially in Pennsylvania, which could be the state that makes the planets and the fates and all the stars align for VP Harris," the mailers read. "We think you belong in the voting booth because we are never going back, like ever."

Former Republican Rep. Liz Cheney responded to former President Donald Trump's attacks on her in an interview with ABC's "The View" on Monday, including a remark he made suggesting she should "have guns trained on her face."

"He knows what he's doing," Cheney said. "He knows it's a threat with the intent to intimidate. Obviously, the intimidation won't work."

Cheney emphasized Trump's history of violent rhetoric, including how he responded to the violence on Jan. 6.

"For over three hours, he watched police officers be brutally beaten. He was told the vice president had been evacuated, he said, 'So what?'" Cheney said. "People were rushing in, pleading with him, 'Tell the mob to leave,' and he wouldn't."

"That level of depravity, he knows he has no defense to that, and he knows that the American people will not entrust again with power anyone who would do something that cruel," she continued. "And so because he can't respond to that, he tries to change the subject, he tries to threaten. It's what autocrats do to try to get their political adversaries to be silent."

JD Vance addressed voters in Wisconsin during a rally in La Crosse on Monday.

"Tomorrow is our last chance," Trump's running mate said. "Tomorrow is the big day when we are going to vote in very big numbers in the state of Wisconsin. We're going to vote for change. We're going to vote for American prosperity."

Minnesota Gov. Tim Walz is also campaigning in Wisconsin on Monday. Vance called it "tough work" to "convince the American people" that Harris can be president.

"I think that's the toughest job in the United States of America," Vance said, saying Harris is "more of the same" high grocery prices, unaffordable housing and "wide open border."
