Two Thirds Of Voters Say President Joe Biden, 80, Should Step Down So Younger Candidates Can Seek His Party's 2024 Nomination, Including More Than Half Of Democrats, A Dailymail.Com/TIPP Poll Shows

• Republicans, Democrats, and independents agree: It's time to go, Joe
• California Gov Gavin Newsom is touted as a better nominee than the president
• Democrats want Biden to debate his long shot rivals, including RFK Jr

Two thirds of voters say Joe Biden is too old to run for a second term as America's president, and he should step aside, so younger Democrats can duke it out for the party's nomination, a DailyMail.com/Tipp Poll shows.

Fully 67 percent of respondents said the 80-year-old president should not run again in 2024, amid concern over the gaffes, trips and falls linked to his age, such as last month's tumble at the US Air Force Academy in Colorado.

The poll bolsters Republican claims that Biden is no longer fit for perhaps the world's most demanding and important job, and as viable Democrats, such as California Gov Gavin Newsom, position themselves to run.

Our survey of 1,214 US adults showed that Republicans were largely convinced that Biden should hand over the keys to the White House — four fifths said it was time for him to step down.

But what's really troublesome for Biden are the 56 percent of supporters for his own Democratic Party that agree.

Only a third of Democratic voters said the president should run again in 2024. Another 10 percent were not sure.

Biden already has two Democratic rivals seeking his party's nomination — the lifestyle guru Marianne Williamson and anti-vaxxer Robert F Kennedy Jr. — but both are seen as long shots at this stage.

In the wings are well-respected younger Democrats who may fare better than Biden against former President Donald Trump, Florida Gov Ron DeSantis, or whichever Republican clinches that party's nomination.

Among them are Newsom, Michigan Gov Gretchen Whitmer, Biden's Vice President Kamala Harris, and his Transport Secretary Pete Buttigieg.

Biden has said that questions about his age are entirely 'legitimate.'

But he's also tried to laugh off concerns that he no longer has the energy or sharpness for the job.

At 80, Biden is already the nation's oldest president. Every day he extends the record.

He is in generally good health and experts say he might even be a 'superager,' one of a small number of people whose cognitive functioning is decades younger than his body.

Republican presidential candidates have been less generous.

Trump, 77, has repeatedly said Biden suffers from dementia. Former South Carolina Gov Nikki Haley, 51, has called for competency tests for candidates over the age of 75.

Our survey had more bad news for Biden's reelection bid.

More than three quarters of respondents said he should take part in a TV debate with the two Democrats who have declared their candidacies — Williamson and Kennedy.

Fully 77 percent of voters want to see Biden square off against those two on stage, polling shows — an unlikely scenario given that the Democratic National Committee (DNC) has said it's not planning a primary debate.

That includes roughly similar numbers of Republican and Democratic voters.

Among Democratic voters, Biden is the clear front-runner, with the support of about 60 percent of liberal voters, according to a CNN/SSRS poll in May.

Biden's White House has largely avoided commenting on the opponents.

That keeps with tradition: no sitting president has taken part in a primary debate in decades, even when facing a well-known challenger.

Still, Kennedy has 20 percent support, Williamson polls at 8 percent and a similar share wants 'someone else.'

Kennedy, a pro-choice former environmental lawyer, has tried to court centrist voters with promises of border security.

He portrays himself as the only viable left-of-center alternative to the aging and gaffe-prone commander-in-chief.

The son of Robert F. Kennedy, an attorney general and senator, has in the past promoted conspiracy theories about the safety of FDA-approved vaccines.

Williamson became a household name through her appearances on The Oprah Winfrey Show and ran in the 2020 presidential nomination contest.

She has railed against Biden and the DNC for rigging the process.
