Why ES_CEN voters lean toward Daniel Hernandez Medina over Almudena Iglesias. 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 Almudena Iglesias's vote can be persuaded across to Daniel Hernandez Medina, and 20.0% of Daniel Hernandez Medina'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 -0.7 pts of that movable slice.
