A single seat, decided on plurality. Ronald Hunt holds 51.8% against 48.2% for the nearest rival.
Why Pennsylvania voters lean toward Katherine Booker over Ronald Hunt. 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 Ronald Hunt's vote can be persuaded across to Katherine Booker, and 20.0% of Katherine Booker'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 0.1 pts of that movable slice.
