Well founded hypothesis:
There is nothing Joe Biden or Kamala Harris legally could have done (in retrospect) to change this outcome in the election because ...
the electorate thinks the White House can control the economy and was responsible for inflation in 2023--something Republicans were happy to atrtribute to the White House falsely.
And that was the deciding factor. Economic literacy is poor in the USA.
@Lulz4l1f3 actually President Biden could have, really should have seized the moment do the equivalent of FDR fireside chats (YouTube etc.) to discuss recovery from the Covid pandemic, the impact on the economy (jobs & prices), and of critical importance all things J6. Pissed away.
@CanisPundit Carter did fireside chats.
People still blamed him. Live and learn.
