SCORE ANATOMY
The statewide 2024 presidential result was R+5.5. The baseline is 0 at a 5-point Democratic margin and 100 at 30 points; only 2024 is retained statewide, so no multi-cycle floor applies.
Not in this score
No retained Senate primary evidence exists, so the structural baseline is the blue baseline alone. Nothing is imputed.
