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."

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.
