A more competitive House
The map was made with 2024 Presidential election data in Dave's Redistricting. Since VRA Section 2 is pretty much overturned, it was not accounted for in my making of the maps.
I aimed for some proportionality in most states, while getting kind of more biased (gerrymandered) one way or the other in some states to spice things up for funsies.
The gradient has 9 shades for increments of 2.5% for margins of anything ≤20%.
113 Seats have a margin of ≤7.5%, competitive range, though 141 are of a margin of ≤10% if you'd cast a wider net, a narrower one of ≤5% contains 86 seats. A swing of 7.5 for the Dems would be ~266 seats, a swing of 7.5 for the Republicans would be ~282 seats.
In real life 2024, iirc, ~11% of seats were generally considered to be competitive, with this map, ~26% of seats could generally be considered competitive.
Iirc, Harris won 205 congressional districts, while Trump won 230. The House elections ended up being 215D-220R.
Anyways, it might be ugly, it might be unethical in some ways, yet I ultimately made it for fun.
