Votes allocated by demographic reach each turn. Final 4 turns = 25%; earlier turns = 75%.
A single seat, decided on plurality. Stephanie McAllister took 52.0% against 48.0% for the nearest rival.
Why New Hampshire voters lean toward Stephanie McAllister over Donald Howard. Each driver is signed: + = lift, − = drag. Drivers are relative within this list and only move the persuadable slice of each party's vote, so their real effect is small. Coattail rows are direct share tilts in %. A raw vote lead does not equal the sum of these bars.
Ceiling this cycle: at most 20.0% of Donald Howard's vote can be persuaded across to Stephanie McAllister, and 20.0% of Stephanie McAllister's vote can be persuaded away. Registration lean sets the starting split and how hard a party is to move, not the final share. These drivers add up to 0.2 pts of that movable slice.
