Sen. Raphael Warnock (D-GA) said Saturday that black voters cannot be taken for granted in the 2024 presidential election between President Joe Biden and his predecessor, Donald Trump.

The Georgia Democrat made the comment as polling data indicate the president’s support is waning among black voters. Just before he appeared on MSNBC to discuss the matter, the network flashed a clip from a USA Today report showing black support for Biden at 56% and 54% in Pennsylvania and Michigan, respectively. Both are states the president will almost certainly need to win to keep the White House, and both figures are 20-point drops from 2020.
