Back in 2020 many postulated that Biden stepping down to let the cackler in was the plan. If he’s out before end of term, cackler will go into the election with a bit of incumbent experience.
I thought the plan was for Biden get re-elected and at the
mid-point + one day of the second term he’d step down. Then
VP became the president and could serve to the end of that term
and be elected for two complete four year terms.
That could still happen if Biden steps down but I don’t think
she would be as likely to be re-elected. Especially with Trump
still in the picture.
