Vice President Kamala Harris has taken a 3-point lead over former President Trump as she gains ground on key issues, according to a new poll.

The poll, conducted by NPR, PBS and Marist, found Harris leading Trump 51% to 48%, but clarified that the difference is within the margin of error. Harris has also narrowed Trump's lead on key issues like the economy.

Trump still holds a significant 6-point lead when it comes to illegal immigration, according to the poll. Meanwhile, Harris leads on abortion issues by a massive 15 points.

The Marist poll was conducted from Aug. 1-4 and advertised a margin of error of 3.4%.

The survey comes days after a Fox News poll found Trump and Harris deadlocked in Pennsylvania, a key swing state for the presidential election.

The state of the race in the Keystone State is similar to where it was in April, when President Biden and Trump were tied 48%-48%. The survey, released Friday, shows Harris and Trump locked in a tie in Pennsylvania at 49%-49% — barely different from what the final election results were in the state in 2020 (49.85% Biden vs. 48.69% Trump).

The poll further showed Trump closing the gap with voters under 30 (-27 points in April to -4 points today), voters 65 and over (-5 to -1), suburban women (-32 to -12) and those with a college degree (-18 to -10), and widening it slightly among independents (+8 to +9).
