Another day has brought yet another poll which shows that a solid majority of American voters believe President Joe Biden is too old to serve a second four-year term in the White House, Breitbart reported.

That has been a consistent finding for pollsters over the past couple of years about the public's perception of Biden, who would be 82 at the beginning of a second term and 86 upon finally leaving office -- if he could serve the entire four years.

However, as some polls have revealed, it isn't so much Biden's advanced age, in and of itself, that has sparked legitimate concerns among most voters, but rather worries about the inevitable -- and increasingly apparent -- physical and mental health decline that so often accompanies old age.

Two-thirds say Biden is "too old" for a second term

On Wednesday, Quinnipiac University released its latest poll of 1,421 self-identified registered voters, which asked respondents to weigh in on President Biden's age plus his physical and mental fitness for office.

A two-thirds majority of 67% said Biden was "too old to effectively serve" another term in the White House, while just 31% said that he was not too old to be re-elected.

As for whether Biden was physically capable of serving out a second term, 62% said "No" while 35% said "Yes," and on the issue of Biden's mental fitness for another four years in office, 64% said he was not mentally fit compared to 34% who believed that he was.

Setting aside the question of whether Biden can effectively serve another term in the White House, the pollsters found that voters are already quite displeased with how he has served in his current term, as his job approval is deep in negative territory with just 40% approval in comparison to 57% disapproval.

That general disapproval also extends to virtually every major individual issue, including his handling of the economy, immigration and border security, and foreign policy, including his response to the two major ongoing conflicts between Ukraine and Russia as well as Israel and Hamas.

Nearly 9 in 10 Americans are concerned about Biden's health

As bad as the Quinnipiac poll results are for President Biden, those numbers are actually better for the incumbent than what NBC News pollsters found earlier this month about how voters feel in terms of the president's physical and mental health status.

That survey found that a combined 89% of 1,000 registered voters polled had some level of concern about "Biden not having the necessary mental and physical health to be president for a second term."

That included 62% with "major" concerns, 14% with "moderate" concerns, and 13% with "minor" concerns. Notably, of the combined 76% with "major" and "moderate" concerns about Biden's physical and mental health, that figure includes not just 95% of Republicans but also 81% of independents and even 54% of his own fellow Democrats.

White House and campaign team likely in panic mode

Breitbart observed that the polls highlighting voter concerns about President Biden's age and health coincide with the recent release of a damning final report from Special Counsel Robert Hur, who was tasked with investigating Biden's apparent unlawful retention of classified documents from his time as a vice president and senator that were stored in unsecured locations like his Delaware home and a Washington D.C. office.

Though Hur determined that Biden had been "willful" in his unauthorized retention of classified materials, he declined to press any criminal charges due to Biden's frequent forgetfulness and questions about his mental competence as well as the presumption that a jury would refuse to convict an "elderly man with a poor memory."

Given that nothing can be done to make Biden any younger, and while efforts to keep his increasingly obvious cognitive decline in check are showing dubious results, at best, the White House and his campaign team are undoubtedly in panic mode about how, or even if, they will be able to push or drag the ancient politician across the finish line in November.
