Vice President Kamala Harris is trailing former President Donald Trump in three crucial swing states, according to two new polls.

With less than ten days until Election Day, the race between Trump and Harris remains extremely close, with the outcome largely dependent on swing states, particularly Pennsylvania. The Keystone State has 19 electoral votes, more than any other swing state.

A recent Emerson College Polling/RealClearWorld poll shows Trump favored in North Carolina and Wisconsin, while a similar Emerson College Polling/RealClearPennsylvania poll shows the former president favored in the Keystone State. Neither poll is great for Harris' campaign, but with Trump's lead within the margin of error, the race is still wide open.

Newsweek reached out to Harris and Trump's campaign via email Friday seeking comment.

FiveThirtyEight ranks Emerson College as the 10th best pollster based on its historical track record and methodology.

Pennsylvania

The poll of 860 likely voters, conducted between October 21 and 22, showed Trump with a one percentage point lead, 49 percent to Harris' 48 percent. Three percent of respondents are undecided. Of undecided voters, 51.6 percent said they leaned toward Harris, while 48.4 percent said they leaned toward Trump. The survey has a margin of error of plus or minus 3.3 percentage points.

The survey found that neither candidate received a majority positive rating. 46.8 percent of respondents viewed Harris at least somewhat positively, while 53.2 percent had a negative opinion of her.

When it comes to Trump, the gap is smaller: 49 percent of those surveyed view him at least somewhat positively and 51 percent have a negative opinion.

Trump narrowly won Pennsylvania against Hillary Clinton in 2016, while President Joe Biden flipped it in 2020. The race in the state is expected to be decided by a few thousand votes, and both major party candidates have repeatedly campaigned there.

The latest aggregate state polls show an extraordinarily narrow gap between Republican and Democratic presidential candidates, with peaks fluctuating within the margin of error, making the state a mess.

Nate Silver's Silver Bulletin estimates Trump is up 0.2 percent in the state, while FiveThirtyEight estimates Trump is up 0.3 percent, 48 percent, to Harris's 47.7 percent. Meanwhile, the New York Times as a whole has Harris leading by less than 1 percent.

North Carolina

A similar poll in North Carolina showed Trump with a slightly larger lead, at 2 percentage points.

The Emerson College Polling/RealClearWorld poll of 950 likely voters in North Carolina, conducted between Oct. 21 and Oct. 22, found that 50 percent support Trump's candidacy while 48 percent support Harris. Three percent are undecided. Trump's lead is again within the poll's margin of error of plus or minus 3.1 percentage points.

Among undecided voters, 36.6 percent lean toward Harris while 63.4 percent lean toward Trump.

The two major party candidates are essentially tied in terms of popularity, with Harris narrowly ahead of Trump. About 49.6 percent of respondents find it at least somewhat positive, while 49.4 percent view Trump at least somewhat positively.

Spencer Kimball, executive director of Emerson College Polling, noted gender patterns among respondents, saying, “In North Carolina, men support Trump by 13 points, while women support Harris by seven points.”

North Carolina has voted for the Republican candidate in the last three presidential elections. She voted for former President Barack Obama in 2008, but not again in 2012.

Several aggregate state polls have shown Trump leading in the state, including FiveThirtyEight, where Trump is ahead of Harris by 1.3 percentage points. While the New York Times and the Silver Bulletin see Trump with a lead of less than 1 percent.

Wisconsin

A poll of 800 likely voters in Wisconsin conducted between October 21 and 22 showed Trump leading Harris within the margin of error, 49 percent to 48 percent. The survey has a margin of error of plus or minus 3.4 percent.

Harris has the majority among undecided voters: 64.9 percent lean toward her, compared to 35 percent who lean toward Trump.

More Wisconsin residents view Trump at least more positively than negatively, while the opposite is true for Harris: 51.4 percent view her negatively and 48.6 percent view her at least somewhat positively. Trump has a simple majority: 50.4 percent of respondents view him positively, while 49.6 percent have a negative opinion of him.

Men support Trump by a slightly smaller majority in the state, while more women prefer Harris than in North Carolina, according to Kimball, who said: “In Wisconsin, men support Trump by 12 points, while women prefer Harris by nine points.”

In 2020, President Biden won the state while Trump won it in 2016. Former President Barack Obama won the state twice, in 2008 and 2012.

In Wisconsin, overall polls are deadlocked. The Hill projects Trump to be ahead by 0.4 percent, while Harris is ahead by a smaller margin of 0.2 percent at FiveThirtyEight. In the Silver Bulletin, Harris is up 0.5 percent, and the New York Times reports Harris at 49 percent versus 48 percent for Trump.

National and aggregate polls provide insight into voter sentiment, but ultimately it is individual states and their votes in the Electoral College that determine the presidential election. To win the presidency, a candidate must receive 270 electoral votes, which does not always correspond to the national popular vote.
