According to a write-up from the poll, with original emphasis:
Our latest hypothetical voting intention finds Donald Trump ahead of Joe Biden, with 42% saying they would vote for Trump (down 2%) and 38% saying they would vote for Biden (down 1%), after weighting by likelihood to vote. Together with our polling from three weeks ago, this poll marks the second lead for Donald Trump over Joe Biden that we have seen in our national polling, including polls conducted in advance of the 2020 Election. A further 16% say they don’t know how they would vote (up 9%).
Large majorities of 2020 Donald Trump voters (86%, down 3%) and Joe Biden voters (79%, up 3%) maintain that they would again vote for those respective candidates.
While this “[l]arge majorities of… voters” would vote for their candidate from 2020 again, it’s worth noting that, even with the drop, Trump still has a 7 point edge against Biden.
The poll surveyed 1,500 eligible voters in the United States and was conducted on December 5.
