Socialist Sen. Bernie Sanders would be open to taking another run at the presidency in 2024 if President Biden decides not to seek a second term, according to a report. ​

The Vermont independent’s intentions were revealed in a campaign memo one of his top political advisers sent to supporters on Wednesday that was obtained by the Washington Post. ​

“In the event of an open 2024 Democratic presidential primary, Sen. Sanders has not ruled out another run for president, so we advise that you answer any questions about 2024 with that in mind,” read the memo from Faiz Shakir, ​who served as Sanders’ campaign manager in 2020.​

Shakir did not respond to a request for comment from the newspaper.​

“While it’s frustrating this private memo leaked to the media, the central fact remains true, which is that Senator Sanders is the most popular office​ ​holder in the country,” Sanders spokesman Mike Casca​ told the Washington Post, adding that their contention is based on polls. 

Sanders, 80, who ran for president in 2016 and 2020 but lost out to Hillary Clinton and Biden respectively, told the Washington Post in May 2020 that the chances of him pursuing the White House again was “very, very slim.”

Biden, 79, reportedly told former President Barack Obama that he plans to run for re-election in 2024, but his job approval numbers are in the basement.

His administration has been struggling with the border crisis, rising consumer costs because of inflation — which hit 8.5% in March the lingering effects of the coronavirus pandemic and Russia’s invasion of Ukraine. 

The Shakir memo also includes a primer titled “Embrace the attacks,” laying out how Democratic campaigns supported by Sanders should respond to criticism over his backing.

“As campaigning heats up in states across the country, your political opponents and their corporate-aligned allies will try to make you feel defensive about Sen. Bernie Sanders’ support for your candidate,”​ Shakir says in the memo.​​

“Our advice is to embrace the attacks​,” he writes.​​

Shakir offers advice for the campaigns on how to answer questions about why their candidate is accepting an endorsement ​from a self-avowed Democratic socialist​.  

“Sen. Sanders is putting forward an extremely popular vision for the Democratic Party that will win back critical support that we have lost​,” Shakir suggested they respond.

​”In fact, Bernie wants to build power for the working class and take on the corporate socialism that our political system currently favors​,” he added.

Shakir also provides a recommendation for how to reply to inquiries about whether their candidate would support Sanders if he runs against Biden in 2024.

“Sen. Sanders is focused on helping Joe Biden have a successful presidency. As Chairman of the Senate Budget Committee, no one fought harder for the president’s policy agenda than Bernie. He traveled to Republican Congressional Districts last summer to promote Build Back Better​,” he says. “Unfortunately, that legislation was stopped by corporate Democrats​.”
