Kamala Harris now leads Generation X, Generation Z, Millennials, Baby Boomers and Silent/Grand Generations in a new poll.

With less than three weeks until the November 5 presidential election, attention is on the poll results. In general, there are incredibly narrow, marginal leads on both sides that suggest a neck-and-neck race.

However, a new Marist poll shows Harris leading the pack among all generations surveyed between October 8 and 10.

About 53 percent of Generation Z (people born between 1997 and 2012) and Millennials (born between 1981 and 1996) said they supported Harris, while over 47 percent said they supported Donald Trump.

Meanwhile, among Baby Boomers (born between 1946 and 1964) and the Silent/Greatest Generation (born between 1901 and 1927), Harris had a 55 percent lead over Trump's 45 percent.

In Marist's previous poll, conducted between September 27 and October 1, Harris also led among these generations, but Trump had a 53 percent majority among Generation X (born between 1965 and 1980).

However, Trump lost that lead in the latest Marist poll, which shows Generation X split at 51 percent for Harris and 48 percent for Harris.

Marist surveyed 2,021 adults consisting of registered voters and likely voters, and the poll has a margin of error of +/- 2.17 percentage points.

It also said that among registered voters surveyed, 38 percent were Democrats, 33 percent were Republicans and 28 percent were independents. Among likely voters, 40 percent were Democrats, 33 percent were Republicans and 26 percent were independents.

Newsweek emailed the Trump and Harris teams outside of normal working hours for comment.

It comes as Trump appears to have gained some momentum in recent swing state polls.

Average polls of 538 show Trump has increased his lead in Arizona in recent weeks, overtaking Harris in North Carolina and even pulling ahead in Nevada. The former president also reduced Harris' lead in Pennsylvania, Michigan and Wisconsin.

Trump had a significant national polling advantage over his Democratic opponent when the party's presidential nominee was President Joe Biden.

But that changed in July after Biden dropped out of the race and endorsed Harris, who quickly closed the gap in several polls.

As of Wednesday, the vice president was ahead of Trump by 2.4 percentage points in the FiveThirtyEight national average, compared to a lead of 3.3 percentage points on September 18.

Similarly, Harris' 49.3 was just ahead of Trump's 46.5, according to statistician Nate Silver's Silver Bulletin blog.

In RealClearPolling, Harris was at 48.7 percent, 1.5 points ahead of Trump, who had 47.2 percent support.

D. Stephen Voss, a political science professor at the University of Kentucky, said Newsweek that the poll numbers “would fluctuate somewhat until election day”.

He said: “It will be tempting to try to add interpretation to every upturn or downturn in a candidate's poll, but in most cases short-term fluctuations in the poll are not meaningful. Pollsters don’t make their decisions in exactly the right order. Just like voters ultimately do.”
