A single seat, decided on plurality. Philipp Navratil holds 61.4% against 38.6% for the nearest rival.
Why Massachusetts voters lean toward Philipp Navratil over Abraham Tripp. 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 Abraham Tripp's vote can be persuaded across to Philipp Navratil, and 20.0% of Philipp Navratil'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 -0.8 pts of that movable slice.
