Seats projected by demographic reach and regional support each turn.
321 seats, apportioned by share. A Hare quota of 121,496 votes buys one seat; 22 of the 321 were settled on largest remainder.
Why DB voters lean toward Chen Lei over Hu Yuzhi. 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 Hu Yuzhi's vote can be persuaded across to Chen Lei, and 20.0% of Chen Lei'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 -1.2 pts of that movable slice.
