President Trump is ahead of all Democratic 2020 candidates in a USA Today/Suffolk University poll published Monday.

Why it matters: The poll of 1,000 registered voters was conducted Dec. 10–14 as House Democrats prepared stepped up their case for the president's impeachment. It's a boost for Trump ahead of the impeachment vote, expected Wednesday.

Worth noting: USA Today points out that political surveys conducted a year out from an election aren't a reliable factor in who's elected president, particularly when a party's nominee has yet to be picked.

"But the findings do indicate that impeachment hearings detailing what critics see as Trump's violations of the Constitution and his oath of office haven't undermined his core political support," the news outlet noted after releasing the new poll, which has a margin of error of 3 percentage points.
