The gender gap among youth supporters of Vice President Harris and former President Trump more than doubled since the spring, a Harvard Institute of Politics youth poll found.

The survey found that the gender gap grew from 8 percentage points in the spring, when President Biden was the Democratic nominee, to 20 points now, with Harris as the party's candidate.

Harris leads by 10 percentage points among men and 30 percentage points among women, the poll revealed.

Among white women, Democrats saw a 9-point gain, with Harris now at 50 percent support compared to Trump's 37 percent, the survey found. In the spring, Trump sat at 27 percent compared to Biden's 31 percent.

Among nonwhite women, Harris sits at 70 percent support, while Trump sits at 15 percent, the poll showed. In the spring, Trump had 15 percent support, while Biden had 36 percent support.

The poll noted Trump leads among young male voters who are less certain about voting, 37 percent to Harris's 26 percent.

For likely voters of this demographic, Harris leads Trump, 55 percent to 38 percent.

The poll also found that among registered voters nationwide, Harris leads Trump by 20 points nationwide, 53 percent to 33 percent. Among likely voters, the divide widens with Harris outpacing Trump, 60 percent to 32 percent.

In key battleground states Arizona, Michigan, Georgia, North Carolina, Pennsylvania, Nevada and Wisconsin, Harris leads among registered voters, 50 percent to 41 percent, the survey revealed. Four percent supported third-party candidates, and 6 percent were undecided.

In the states that Biden won in 2020, the survey found Harris leads by 34 percentage points, but in the states that Trump won, her lead shrinks to 10 percentage points.

The poll surveyed 2,001 adults under 30 from Oct. 3-14. The margin of error for the total sample was 2.64 percentage points. For registered voters, the margin of error was 3.05 points, and it was 3.61 points for likely voters.
