A single Missouri state house district's presidential baseline — what the cycle-by-cycle margin shows about the district as currently…
Scroll to read the full answer
State House District 155 voted D+14.6 in 2024, running 16.3 points to the left of Pennsylvania's R+1.7 statewide margin — the parent state went red while the district held a double-digit Democratic lean. The trajectory has bent right by 7.0 points off the 2020 peak of D+16.5, but the district still tracks Chester County (D+14.5) almost exactly and sits 16.0 points clear of PA-6's D+11.4. A divergence that wide between a 108K-population shape and its containing state usually points to a block-group-level pattern doing the work.
