Republicans are outpacing Democrats in in-person early voting in Nevada while Democrats are outpacing Republicans in mail-in voting, the Nevada Secretary of State Office's latest report shows.

The latest report, updated Monday night, reflects early in-person voting and mail-in voting turnout in the first three days. It showed 52% of in-person early voters so far have been Republicans, while 28% were Democrats. Of all mail-in ballots cast so far, 43% so far have been Democrats and 30% Republicans.

The pattern reflects trends from the 2020 presidential election, when Republicans outpaced Democrats in early in-person voting and Democrats outpaced Republicans with mail-in voting.

In total, 245,356 mail-in ballots and early in-person ballots had been cast as of Monday night, with just under 40% of them being Republicans and 36% of them being Democrats.

In-person early voting in Nevada began on Oct. 19.

In the final sprint of the election campaign, local officials in the key battleground state of Pennsylvania have mounted an unprecedented push to engage some of the state's newest and untested voters: 18-year-old high school seniors.

"They're the largest registered bloc of voters in the city. It's just a matter of getting them energized to come out and turn out to vote," said Philadelphia City Commissioner Seth Bluestein.

Fewer than half of 18- and 19-year-old voters nationwide cast ballots in the 2020 election, according to the Center for Information and Research on Learning and Engagement at Tufts University.

At Martin Luther King High School in Germantown, Pennsylvania, ABC News joined hundreds of high school seniors assembled for an outdoor field day of election-themed activities.

"I am following the political election a lot. I am into the debates, and I am watching the debates. So I do feel pretty positive about who I'm taking on voting for this year," said Jymirah Wood.

"I'm not, like, someone who's super duper political myself," Simmons said, "but I feel like in this year with the election, it's really important because so many changes can happen depending on who wins."

Elon Musk's America PAC said late Monday that it handed out a third $1 million check to a voter who has signed its petition backing the Constitution.

The PAC said in a post to X that the check was given to Shannon Tomei from McKees Rocks, Pennsylvania, posting a photograph of Tomei holding the check.

"Every day until Election Day, a person who signs the petition will be selected to earn $1M as a spokesperson for America PAC," it added.

Musk shared the announcement and congratulated Tomei. In other posts, he has been urging people to register to vote in Pennsylvania -- a crucial battleground state in next month's presidential election.

The first two winners were announced during a town hall in Harrisburg, Pennsylvania, over the weekend, with Musk handing over the checks to the winners on stage. It's unclear how the third check was delivered.

Musk has thrown his weight behind former President Donald Trump and the Republican Party, describing Trump as the only candidate "to preserve democracy in America."

Vice President Kamala Harris and former Rep. Liz Cheney capped off their battleground tour in a suburb of Milwaukee, Wisconsin, in their bid to appeal to moderate Republicans and independents.

During the final event on Monday, Harris continued to draw a contrast between herself and former President Trump and even poked fun at his dance moves during his campaign rally last week.

Harris, who called Trump's onstage dancing a "solo dance," said that it was proof that the former president is "increasingly unstable."

“What we see about him in public, whether it be his rallies or, as you said, the -- what would it be called? -- just a solo dance? I don't know,” said Harris, drawing laughter from the crowd.

"I think it does lead us, and it should lead us, to observe that he is increasingly unstable," Harris said.

Harris was referencing Trump's town hall in Oaks, Pennsylvania, last week where two medical emergencies in the crowd interrupted the event, which eventually turned into what his campaign at the time called an "impromptu concert."
