I’m going to assume this is a good faith question. What’s wrong with Harris is that she is essentially polling the exact same as Biden despite not being blamed for inflation, the Gaza invasion, the withdrawal from Afghanistan, appearing senial in a debate, not being old, etc. That is to say that despite having none of that baggage hanging over her head, she essentially has the same chances of winning as Biden.
That’s a reasonable take and I appreciate you taking the time to share. I can see your point that increasing the uncertainty means that the new DNC candidate has an opportunity to pick up a larger share once the unsure voters pick. This seems like a sort of mutated version of the gamblers fallacy to me.
Having a larger uncertainty pool doesn’t really provide any advantage for Democrats. While theres opportunity for the DNC candidate to pick up votes from this pool of voters there’s also opportunity for Trump to pick up votes once they know more about the other candidates.
Without more information the most likely outcome is Trump picks up about 51.5% of undecided voters and the other candidate picks up about 48.5%. If we know why these voters are unsure then we can make a more educated guess about how they might vote for each candidate and we might be able to say the DNC candidate will pick up the required votes.
Unfortunately we don’t know why they’re unsure so saying that the best thing Biden can do is drop out just isn’t supported by the information available.
On a personal note I think Biden should announce he’s old and tired and just doesn’t have 4 more years of being president in him. After that drop out of the campaign, endorse another candidate, and announce a clear plan for how the DNC is going to actually select the next candidate.
If he doesn’t make it extremely clear that dropping out his decision, or there’s no clear and transparant plan on how the next candidate will be selected, then it’s going to start a civil war in the DNC that will hand the presidency to Trump.
