Less than 40 percent of U.S. voters think President Joe Biden is in charge of his administration, according to a Rasmussen Reports poll released Friday.

This survey follows a Reuters/Ipsos poll that found Biden’s approval ratings dropped by seven percentage points. It reached its lowest point since the Taliban took control of Afghanistan after the U.S. troop withdrawal.

Rasmussen Reports surveyed 1,000 voters to find out how confident they were that Joe Biden was physically and mentally ready for the job of President of the United States.

Fifty-two percent said ”not very” (11 percent) or ”not at all” (41 percent) confident. Just 46 percent said they were ”very” (32 percent) or ”somewhat” (14 percent) confident.

When asked, ”Is Joe Biden really doing the job of president, or are others making decisions for him behind the scenes?” 39 percent said, ”Joe Biden is really doing the job of president,” while 51 percent said, ”others are making decisions for him.”

According to Reuters, Biden’s approval fell as the Taliban invaded Kabul. This wiped out two decades of U.S. military involvement that has cost taxpayers nearly 1 trillion dollars and thousands of American deaths.

Many conservatives are unsure who is really in charge of the White House. They also question Biden’s mental ability to serve and age. A New York Times piece published in July suggested that Ron Klain, Biden’s White House chief of staff, was the man steering the administration.

According to the article, Republicans have started to refer to Klain as their ”prime minister”.

Rasmussen Reports conducted the Rasmussen survey on 1,000 likely voters in the U.S. between August 18-19, 2021. With a confidence level of 95%, the margin of sampling error is +/– 3 percentage points.
