The President also lags behind television personality Oprah Winfrey between 41 to 52 percent.
Political observers have said that Biden and Sanders are yet to rule out their bids in 2020 elections.
CNN reported earlier in January that Winfrey was "actively thinking" about running for the post.
Trump speculated earlier that he could defeat Winfrey in 2020 elections if she ran, following her speech at the Golden Globes awards in support of the "Time's Up" movement.
"Yeah, I'll beat Oprah, I like Oprah. I don't think she's going to run," Trump said.
In terms of highest favourability rating, Winfrey was the highest at 64 percent, followed by Biden with 58 percent and Sanders with 57 percent. (ANI)
