2024 election updates: Millions have voted early as Trump, Harris sprint to finish

David Plouffe, a senior adviser to Vice President Kamala Harris, told CNN’s Erin Burnett on Monday night that the campaign believes it could win all seven swing states.

“It’s very important that we have multiple pathways to 270, and you know, just a couple hours ago, reviewing all the early vote data, what we're projecting for Election Day, how we think undecideds are breaking, we have a credible pathway to all seven states tomorrow night to go into Kamala Harris' column," Plouffe said.

"But we believe they're all going to be close,” he added.

Asked if he believes Harris could win all seven states, he said, “Yes.”

Plouffe said that the campaign believes it is winning more late-breaking voters than former President Donald Trump is, and he credits the campaigns’ different approaches to their field operations.

“I think outsourcing your field effort -- meaning the folks knocking on doors, making calls – largely to exclusively paid canvassers, historically just doesn’t work,” he said. “You want people showing up who are committed to your candidate."

He called that a "secret weapon for us" and said that volunteers were "knocking on 2,000 doors a minute in Pennsylvania over the weekend."

But, he acknowledged, both campaigns “have a lot riding on tomorrow, on actual Election Day.”

Vice President Kamala Harris visited a Puerto Rican restaurant in Reading, Pennsylvania, Monday night, accompanied by the state's governor, Josh Shapiro, and Rep. Alexandria Ocasio-Cortez of New York.

A woman, who appeared to be the owner of the restaurant, Old San Juan Cafe, showed Harris a spread of food.

The vice president joked, "I’m very hungry. I don’t get a chance to eat as often as I’d like."

Later, Harris and Ocasio-Cortez huddled with the restaurant owner to discuss the rapid growth of Latino-owned small businesses.

Joe Rogan has endorsed former President Donald Trump in the 2024 presidential election.

The podcast host's endorsement accompanied the release of a three-hour-long interview with Elon Musk, making the case for his support for Trump.

"The great and powerful @elonmusk. If it wasn't for him we'd be f-----. He makes what I think is the most compelling case for Trump you'll hear, and I agree with him every step of the way," Rogan wrote.

"For the record, yes, that's an endorsement of Trump. Enjoy the podcast," he continued.

Michelle Obama went on social media to share a “message to all the young people out there,” encouraging them to vote for Vice President Kamala Harris as the next president of the United States.

“Look, I know it’s easy to feel what we do doesn’t matter. Like the world’s problems are too big and complicated to tackle. Like nothing’s ever going to change at all," she said in a video, pointing to contentious issues like reproductive health rights and climate change.

"That’s exactly why you have to vote: because we need a better leader than Donald Trump. We simply cannot afford another four years of his incompetence, weakness, and division," she added.

The former first lady goes on to say that Harris is the opposite — suggesting that the Democratic presidential candidate will "expand your freedoms" and "protect the planet."

"While he denigrates anyone who is different than him, while he looks out only for himself, Kamala will be a president for all Americans. I know she will listen to you. And that’s why you have to vote for Kamala Harris and Tim Walz on November the 5th,” she said, before urging young people to make a plan to vote on Election Day.
