The survey was carried by Politico and Morning Consult and published on Wednesday, one day before the first anniversary of Biden's inauguration.
Asked to give the president a report card for his first year running the country, the largest share of respondents -- 37 percent -- failed him. Twenty percent gave Biden a "B" and 18 percent graded him a "C." The smallest share of people interviewed, 11 percent, gave him top marks.
In another blow, 52 percent of Americans surveyed say they view Biden as a "weak leader."
A year full of crises -- including a record number of migrants straining local infrastructure at the southern border, an increasingly aggressive Russia, and out-of-control inflation that's reached its highest point in 40 years -- have served to unnerve the 79-year-old president's character despite him coming to power pledging to revert the United States' place in the world and heal political divisions.

Wednesday's new poll also shows Americans' growing concern that the president may just be incompetent to perform his day-to-day tasks, one year after becoming the oldest person sworn into office.

Across multiple survey questions, more than 50 percent of voters have indicated they don't think Biden is energetic, a clear communicator or in good health.
More than a third have expressed concern he's not mentally fit or stable. Possibly more striking is how many people are challenging whether Biden is going to keep his promise, despite years of building an authentic and sincere public image.
