These charts reflect the results of a new CNN / SSRS Poll -- done between January 10th and February 6th of a national sample of 1,527 adults, with a 3.3 margin of error for the entire sample (it would be slightly higher for just Republicans or Democrats).
It shows that neither President Joe Biden nor Donald Trump has really strong support for the 2024 presidential nomination. Only about half of their respective parties want them re-nominates.
