A flurry of polls released Sunday show Vice President Kamala Harris and former President Donald Trump remain poised for a photo finish in this week’s presidential election, with voters narrowly split both nationally and across the pivotal swing states that will decide the election.

There were some encouraging signs for the Democratic nominee, with the final poll from ABC News and Ipsos giving Harris a 49%-46% edge nationally, while the New York Times/Siena survey released Sunday showing Harris ahead in five of seven swing states.

A poll by the Des Moines Register showing Harris with a 47%-44% lead in Iowa — a state Trump has won in each of his prior elections — was likely an outlier, but suggested the vice president could be succeeding in her efforts to make inroads with White voters in the Midwest.

Still, Harris’ advantage across all of the surveys was within the margin of error, and a NBC News poll released Sunday showed the race deadlocked 49%-49%.

Both candidates are campaigning like the race remains on a knife’s edge: Harris spoke at a church service and is holding a campaign rally at Michigan State University, while Trump has rallied in Pennsylvania before heading to events in North Carolina and Georgia.

Both are expected to strongly emphasize their competing economic platforms across the events, especially with the polls showing at least one consensus — that the economy remains the top concern for voters.

Data released last week showed that the U.S. economy continued to grow as inflation cooled and the U.S. added jobs, albeit at a slower-than-expected pace due to a pair of major hurricanes and strikes by aircraft machinists that weighed on employment data.

Here’s what is happening on the campaign trail:

‘Shouldn’t have left’

At a rally in Lititz, Pennsylvania, Trump spent large swaths of his speech suggesting, without evidence, that the election system, polling firms and media were corrupt and conspiring against his campaign — the latest signal that the former president is gearing up to contest the results of the election if he didn’t prevail.

The former president even suggested he should not have departed the White House after losing the 2020 election to President Joe Biden.

“I shouldn’t have left, I mean, honestly,” Trump said. “We did so well.”

Trump’s campaign has pointed to his departure to refute questions about his role in the Jan. 6, 2021, attempted insurrection and dismiss queries about whether he’d accept the results of this year’s contest.

Trump, whose teleprompter had technical difficulties, devoted copious time to denouncing early voting, even as his advisers have pointed to higher turnout among Republican early voters to suggest his campaign has momentum. He said he believed voting should only be held on Election Day, with results certified immediately that night.

“Everyone’s afraid to damn talk about it, and then they accuse you of being a conspiracy theorist,” Trump said.

Trump went on to say he believed the U.S. voting system was worse than in developing countries, and complained his top campaign aides needed to spend time strategizing about challenging election procedures rather than campaign spending or rally locations.

Bulletproof glass

Trump also raised eyebrows during his remarks with a long riff about the bulletproof glass he’s now mandated to use at outdoor events following the attempted assassination in July, where he was shot in the ear.

Trump commented on the amount of ballistic material surrounding his stage, at one point questioning a panel by saying: “To get to me, somebody would have to shoot through fake news, and I don’t mind that much, because, I don’t mind.”

The former president’s campaign hastily issued a statement saying Trump’s comments weren’t intended to suggest he would be accept members of the news media being targeted.

“The President’s statement about protective glass placement has nothing to do with the media being harmed, or anything else,” Trump Campaign Communications Director Steven Cheung said in a statement. “In fact, President Trump was stating that the media was in danger, in that they were protecting him and, therefore, were in great danger themselves, and should have had a glass protective shield, also,” he continued.

Trump courts women

Surveys have shown a stark gender divide among the electorate, with women rallying behind Harris while Trump holds a similar advantage with men.

Ahead of his Lititz event, Trump featured a slate of high-profile female supporters as he looked to cut into Democrats’ advantage. Speakers included former professional race car driver Danica Patrick, former ESPN anchor Sage Steele, former Democratic congresswoman Tulsi Gabbard, and Arkansas Governor Sarah Huckabee Sanders, who served as Trump’s White House press secretary.

The Trump campaign has sought to exploit comments by billionaire Mark Cuban, a top Harris surrogate, who said on ABC’s "The View" last week that Trump is “never” around any “strong and intelligent women.”

Trump, who has been found liable for sexual abuse, has often undercut his own efforts — including suggesting at a recent rally that women should be protected “whether the women like it or not.”

Black voters

Harris, who has seen Trump chip into her advantage with Black voters, visited the Greater Emmanuel Institutional Church of God’s service in Detroit and told worshipers that Black churches were essential in driving the nation’s progress.

“As a nation we face real challenges. We face real challenges, we carry real burdens, we feel real pain, and we must remember that faith combined with our actions, gives us power,” Harris said.

Trump has stressed the bite of inflation and some of Harris’ progressive social policies as he’s pursued a broader coalition of voters. Surveys suggest that Black men in particular are supporting him at a higher clip than any other Republican candidate in recent history.

Harris asked the assembled crowd to support their shared values by turning out to vote.

“Let us turn the page and write the next chapter of our history,” she said.

Election eve concerts

Harris is planning a pair of rallies in Pittsburgh and Philadelphia to wrap up her campaign, and will be leaning heavily on her celebrity supporters to help drive attendance.

In Pittsburgh, Katy Perry will lead a lineup that also includes D-Nice and Andra Day. At Harris’ final event in Philadelphia, Lady Gaga headlines performances that feature hometown acts such as The Roots and DJ Jazzy Jeff. Talk-show icon Oprah Winfrey and Ricky Martin are also expected to attend.

In North Carolina, the campaign is hosting a concert with singer-songwriter James Taylor and "American Idol" stars Fantasia Barrino and Remi Wolf.

Harris votes

Harris revealed to reporters that she had submitted an absentee ballot to California, but declined to say how she voted on a pivotal ballot measure.

Proposition 36, endorsed by the state’s Republican Party, would impose harsher sentences for those convicted of repeat drug or retail theft offenses. Harris has avoided weighing in on the measure, likely seeing little political upside in wading into concerns over crime in the state that Trump has used as a cudgel during the campaign.

“I am not going to talk about the vote on that, because, honestly, it’s the Sunday before the election, and I don’t intend to create an endorsement one way or another around it,” she said.
