Like with the County Mayor election this precinct map is not mine, this is Justin Miller's map. Miller is Salt Lake County Mayor Ben McAdam's campaign manager.
As before, the light blue/red areas are 1-10% for the winning candidate, and the darker a precinct gets, the more it went for a candidate. Note that Salt Lake City is specifically excluded from this district, yet Matheson still won the portion of UT-04 in Salt Lake County 52.25%-44.93%, with Libertarian Jim Vein getting 2.68%.
