A new poll finds eight in ten swing-state voters believe President Joe Biden is too old to run again, a serious warning sign for the 81-year-old president who will need to convince voters in those key states to vote for him in order to win the 2024 election. 

The Bloomberg News/Morning Consult poll conducted in mid-February across seven critical swing-states found voters across every demographic including some of the more reliable Democratic party constituencies believe the president is too old.

It comes as the Biden administration has been pushing back on concerns over the president’s age and mental acuity after the Special Counsel Robert Hur report earlier this month described the president as an ‘elderly man with poor memory.’

On Wednesday, Biden had a physical and his doctor declare him ‘fit for duty’ describing the president as a ‘healthy active, robust 81-year-old.’

The White House had confirmed the president did not take a cognitive test as part of his exam, but Physician to the President, Dr. Kevin O’Connor, did say that Biden did sit for ‘an extremely detailed neurological exam.’

But even among those who did say they plan to vote for Biden, seven in 10 say he is ‘too old.’ 

Less than half of respondents said that Biden’s likely GOP rival former President Donald Trump at 77-years-old is too old.

The polling found Trump leads Biden across all seven battleground states: Arizona, Georgia, Michigan, Nevada, North Carolina, Pennsylvania and Wisconsin.

While the economy remains the top issue, concern over immigration has ticked up across every swing state.

The polling found the majority of swing-state voters blame Biden and congressional Democrats for the surge in migrants. 

At the same time, blame for congressional Republicans and the Trump administration, though much lower, have also ticked up 5 percent from January after Republicans tanked the bipartisan border deal with Trump’s encouragement. 

Biden and Trump are both headed to the southern border on Thursday where they will hold dueling events. The president is headed to Brownsville, Texas. Trump is headed to Eagle Pass which has been ground zero of a border fight between Republican Texas Governor Greg Abbott and the Biden administration. 

While Republicans have blasted the administration over immigration, the White House has pushed back blaming hardline Republicans for crushing a bipartisan Senate deal to address the border earlier this year.

While Biden is facing growing blame over the border crisis and the vast majority are concerned about his age, Trump is not without his own vulnerabilities. 

Nearly six in ten swing-state voters believe Trump is ‘dangerous.’ Even among those who plan to vote for the former president, 28 percent agreed Trump is dangerous. 

As many of half of swing-state voters also say they would be unwilling to vote for Trump if he is convicted of a crime. 

The former president is facing 91 criminal charges in four separate cases involving allegations over hush money payments to porn star Stormy Daniels, mishandling classified documents and efforts to overturn the 2020 election.
