Amid an increasingly tight election between Vice President Kamala Harris and former President Donald Trump in several key swing states, Nebraska, and more specifically, its 2nd Congressional District, has taken on an outsize role in this year's presidential election.

Because Nebraska currently awards three of its five Electoral College votes based on the results in each of its three congressional districts, the so-called "blue dot," as the 2nd district has come to be known, could be critical to either campaign's path to 270 electoral votes.

House Minority Leader Hakeem Jeffries told "Good Morning America" on Monday that Democrats are "on the right side" of the presidential election's most pressing issues.

"The extreme MAGA Republicans have clearly and unequivocally articulated what they will do to America moving forward," Jeffries said.

"They will take a blow torch to social security, they will take a blow torch to Medicare, they will take a blow torch to the Affordable Care Act," Jeffries said.

Vice President Kamala Harris, Jeffries said, is "closing with a positive vision" while former President Donald Trump and his Republican party are "trying to tear us apart."

Jeffries will become House speaker if Democrats win back control of the chamber this week.

"The majority of current House Republicans voted not to certify the election in 2020," Jeffries said. "My colleagues on the other side of the aisle don't seem to be capable of unequivocally saying that they will certify the election and the verdict that is rendered by the American people."

"As House Democrats, that's what we will do," Jeffries added.

"We believe in democracy even when we disagree with the outcome. That's been part of what's made America the greatest democracy in the history of the world."

Highlighting how important Pennsylvania and its 19 electoral votes are to her campaign, Kamala Harris is spending her last full day on the trail with multiple events in the state.

Her search for voters includes a rally in Allentown and then she ends with an event in Philadelphia.

Donald Trump is trying to shore up support in battleground North Carolina – where Harris has made inroads – for a rally in Raleigh, before he, too, heads to Pennsylvania for events in Reading and Pittsburgh before ending his final day campaigning in Grand Rapids, Michigan.

As of 5:30 a.m. ET on Monday, more than 78 million Americans have voted early (a combination of absentee and early, in-person totals), according to the Election Lab at the University of Florida.

The total breaks down into 42,654,364 in-person early votes and 35,348,858 mail ballots returned.

The number of in-person early votes has surpassed 2020's total number of in-person early votes. However, the overall number of early votes so far (including mail-in and absentee ballots) is still lower than 2020’s overall number.
