JOE Biden's secret polling had Donald Trump destroying the president while he stayed in the 2024 presidential race.
The figures were so dire that Biden would have likely even lost his home state of deep-blue - and been hammered in the battleground swing states.
The internal polling taken before Biden dropped out was revealed by former Barack Obama speechwriter Jon Favreau on the .
"Joe Biden's decision to run for president again was a catastrophic mistake," Favreau said.
"He and his inner circle refused to believe the polls, refused to believe he was unpopular, they refused to acknowledge until very late that anyone could be upset about inflation."
Favreau revealed that the White House was telling reporters that Harris could not win the election and Biden was the strongest candidate.

But Biden's internal polling was uncovered after the Harris campaign took over the Biden campaign's operations.
It showed "Donald Trump was going to win 400 electoral votes," Favreau said.

Biden would have even lost his home state of Delaware, which he has been so strongly associated with over his 50 years of public life.
Delaware hasn't given its electoral college votes to a since George HW Bush trounced Michael Dukakis in 1988.
That year, Bush won 426 electoral college votes and 53 percent of the popular vote.

Trump is set to win the 2024 popular vote by just under two percentage points - the first time a Republican has won it since 2004.
The internal polling revelation comes as the dissect how they lost the election.
Biden and his team have come under fire for staying in the race for so long despite knowing the president was so unpopular.
That gave less time to campaign and also prevented a primary where a stronger candidate from the party could have beaten the VP to the nomination.
Biden was forced to drop out of the election race in July after questions swirled about his cognitive abilities.
He bombed in his June debate against Trump after bumbling his way through answers.
Democrats described the debate as an "unmitigated disaster," "a meltdown," and "a slow-motion car crash."
Biden eventually succumbed to the pressure and dropped out of the race - quickly endorsing Harris.
Despite dropping out, Biden still was gaffe-laden on the campaign trail referring to Trump's voters as "garbage."
Speaking after Harris lost on Wednesday, Biden said he had spoken with Trump to congratulate him and "expressed his commitment to ensuring a smooth transition."

Joe Biden's full letter announcing his withdrawal from campaign
On July 21, President Joe Biden posted a letter X, formerly known as Twitter, announcing he's stepping down from the 2024 presidential race.
My Fellow Americans,
Over the past three and a half years, we have made great progress as a Nation.
Today, America has the strongest economy in the world. We've made historic investments in rebuilding our Nation, in lowering prescription drug costs for seniors, and in expanding affordable health care to a record number of Americans. We've provided critically needed care to a million veterans exposed to toxic substances. Passed the first gun safety law in 30 years. Appointed the first African American woman to the Supreme Court. And passed the most significant climate legislation in the history of the world. America has never been better positioned to lead than we are today.
I know none of this could have been done without you, the American people. Together, we overcame a once in a century pandemic and the worst economic crisis since the Great Depression. We've protected and preserved our Democracy. And we've revitalized and strengthened our alliances around the world.
It has been the greatest honor of my life to serve as your President. And while it has been my intention to seek reelection, I believe it is in the best interest of my party and the country for me to stand down and to focus solely on fulfilling my duties as President for the remainder of my term.
I will speak to the Nation later this week in more detail about my decision.
For now, let me express my deepest gratitude to all those who have worked so hard to see me reelected. I want to thank Vice President Kamala Harris for being an extraordinary partner in all this work. And let me express my heartfelt appreciation to the American people for the faith and trust you have placed in me.
I believe today what I always have: that there is nothing America can't do - when we do it together.
We just have to remember we are the United States of America.
