In the 2024 Democratic presidential primary, President Biden receives 73 percent support among Democrats and Democratic leaning voters, environmental lawyer and anti-vaccine activist Robert F. Kennedy, Jr. receives 11 percent support, and author Marianne Williamson receives 8 percent support.

Among Democrats and Democratic leaning voters who support a candidate in the 2024 Democratic presidential primary, 39 percent say they are firmly set on their choice for the Democratic nomination no matter what happens leading up to the Democratic primary, while 58 percent say they might change their candidate choice depending on what happens leading up to the Democratic primary.

Among those voters supporting Biden in the Democratic primary, 51 percent say they might change their candidate choice depending on what happens leading up to the Democratic primary, while 46 percent say they are firmly set on Biden no matter what happens leading up to the Democratic primary.

[That is not a vote of confidence in an incumbent. That’s actually a very bad number if Biden ends up on the ticket in 2024. Two-thirds of Trump’s voters, in comparison, say they are adamant about that choice. — Ed]
