A newly leaked Democratic Party “autopsy” is turning heads for what it says the Biden White House prioritized and what it didn’t, painting a picture of a campaign machine that treated then-First Lady Jill Biden like a top-line political asset while Vice President Kamala Harris was left flat-footed when Democrats suddenly needed her to carry the ticket.
The 192-page dossier, commissioned by the Democratic National Committee, says the White House ordered extensive polling on the settings, issues and messaging Dr. Jill Biden should use to bolster her husband’s presidency. But the report says there was no comparable effort to evaluate Harris, test her messaging, or build a research backbone for a future campaign.
That gap turned into a scramble in July 2024 when President Joe Biden stepped aside and Harris was thrust into the nomination fight with the clock already ticking. According to the report, pollsters rushed three emergency studies into the field after the switch because the pipeline was empty.
Veteran Democratic strategist Paul Rivera, who authored the report, called it a “massive missed opportunity” and said the White House never positioned its own vice president to take the baton.
“As a result, at the moment of the candidate switch the polling team discovered there was no self-research on the Vice President to guide the development of the research instruments,” Rivera wrote. “An incumbent Vice President. With no research to share once she became the nominee.”
Rivera argued that years of runway were wasted. “Had the White House explored and evaluated ways to leverage Kamala Harris earlier in the administration, perhaps it would have improved the President’s standing, and it certainly could have helped prepare her to lead the ticket,” he wrote.
The report also faults the Biden White House for not pushing back hard enough as Republicans branded Harris the administration’s “border czar” during the peak of the migrant crisis, a political albatross that hung over her as voters hammered Democrats on the border.
Rivera said the communication failures ran deeper than one label. “The national campaign did not effectively drive Trump’s negatives, and the White House did not effectively support Vice President Harris over three and a half years to improve her standing before the candidate switch,” he wrote.
NOW: The Democratic National Committee has CAVED and RELEASED the 2024 autopsy report covering Kamala Harris’ pathetic loss, and DNC Chair Ken Martin is FURIOUS

And the document’s assessment of Biden’s own message machine is equally blunt, arguing that “Bidenomics” branding tied the president personally by name to voter frustration over the cost of everyday basics, including groceries.
Perhaps the most damaging conclusion for Democrats is the report’s warning that the party could have faced “even steeper challenges” down-ballot had Biden stayed in the race after his widely criticized June 2024 debate performance. The report says dial-testing during that debate “demonstrated the weakness of the President’s performance.”

Biden ultimately became the first incumbent president to drop a re-election bid since Lyndon B. Johnson in 1968, leaving Harris about 107 days to build a national campaign against a Trump operation that was already fully built and battle-ready.
The dossier itself became a political headache inside Democratic leadership. DNC Chair Ken Martin initially resisted publishing it, then reversed course after blowback from within the party. Martin later acknowledged that burying it sparked its own storm, saying he created “an even bigger distraction.”
CNN published the report with annotations from the DNC disputing the accuracy of multiple claims, underscoring just how raw the intraparty finger-pointing remains as Democrats sift through what went wrong and who, exactly, was calling the shots when it mattered most.
