President Joe Biden is heading into election year showing “alarming weakness” among “stalwarts” of the Democrat base — black, Hispanic, and young voters, according to a new poll.

The USA Today/Suffolk University poll showed that one in five black voters would support a third-party candidate in 2024.

In addition, Biden has fallen behind former President Donald Trump, the likely Republican nominee, with Hispanic and young voters, 39-34 percent and 37-33 percent, respectively. Both groups backed Biden in 2020.

Trump has the support of 12 percent of black voters, the same percentage he had in 2020, according to the poll.

The survey included 1,000 likely voters and was conducted by landline and cell phone Tuesday through Friday last week, having a margin of error of ± 3.1 points.
