The poll asked adults: “In your opinion, how likely is it that Joe Biden will complete his first term in office?”

Predictably, most Americans (71%) said Biden was likely to last through his four years. But 21%, or one in five, said it was “not likely” he would last.

A closer look at the data provides little comfort for Biden’s own pollsters and political advisers.

Just 45% of those responding said it was “very likely” Biden would last. Some 25% said it was only “somewhat likely,” hardly a vote of confidence in Biden’s presidential future. Another 8% said they are “not sure.”
