The correlation is strongest in NYC-DSA races

The correlation is positive everywhere and strongest where NYC-DSA endorsed and ran their own field operation.

Each dot is a district's precinct-level Pearson correlation coefficient between its 2025 first-time-voter share and the endorsed candidate's vote share— higher means the two lined up more closely, precinct by precinct. The correlation is weakened in NY-07, NY-10, and AD-56, where heavily Orthodox precincts had high 2025 first-timer shares.
