President Biden is narrowly leading former President Trump by 4 points in a new survey of young voters — a key demographic Biden carried in 2020.

The Axios-Generation Lab survey of voters under 35 found that 52 percent of respondents would vote for Biden if the election was held today, while 48 percent would back Trump. The survey noted that 70 percent of respondents said they were definitely planning or likely going to vote, while 30 percent said they were unlikely or not planning on voting.

It is the latest of numerous polls showing a close race between Biden and Trump among young voters, who overwhelmingly backed Biden in 2020. Axios noted that a Pew Research Center analysis found Gen Z and millennial voters strongly supported Biden over Trump in 2020, by a margin of 20 percentage points.

A New York Times/Siena poll in December found Trump leading Biden by 6 percentage points among voters under 30. Other polls have also suggested Biden could be losing ground among young voters, with an NBC News poll in November finding Trump leading Biden by 4 percentage points among voters under 35.

Axios noted that Biden's lead in the new poll increased among those who say they are definitely planning on voting; among the 42 percent who say they definitely plan to vote in November, Axios said 63 percent would back Biden.

The new poll also asked young voters how much influence they believe pop star Taylor Swift could have on the election if she chooses to endorse a candidate. The New York Times reported earlier this year that the Biden campaign was seeking her endorsement, but she has yet to speak out on the race.

The survey released Monday found 4 percent of young voters would consider changing their vote if Swift endorsed Biden or Trump. When asked whether they would be more likely to vote in the election if Swift told them too, 6 percent said they would.

The poll was conducted Feb. 3-14 among 1,073 people between 18 and 34 and has a margin of error of 3 percentage points.
