Hillary Clinton gave an interview saying Biden's decision to run for reelection in 2024 was a 'terrible mistake' and cost Democrats the general election, arguing that a nominee selected through a competitive primary would have beaten Trump. The claim is verified across multiple major outlets including The Guardian, New York Times, and The Hill. What's missing from the headline is that this is Clinton's counterfactual opinion about what *might* have happened with a different nominee—factually, Harris did lose and Republicans gained ground, but whether a different nominee would have prevailed is untestable political analysis, not established fact.
