WE GOT IT RIGHT! There is an objectively correct and incorrect answer here, and we resoundingly were on the right side of history.

Quick Look

Basic Stats

Is this different from a 50/50 split? Yes. Exact binomial test p‑value = 9.11^{-4}.

“Over” share 95% CI: [0.64, 0.95].

How many voters would need to switch to change the winner? Because each switch changes the margin by 2, you’d need 9 people to switch from Over to Under to flip the result. A perfect tie isn’t possible with 25 voters.
