The discrepancy resulted from Hamilton County's use of parcel boundaries rather than census units. Consequently, several hundred voters had been assigned to incorrect districts for legislative or local elections. The Hamilton County Election Commission enacted a provisional redistricting that adjusted precinct boundaries countywide and was used only for the 2018 general election. Precinct boundaries were then fully aligned with census units over the course of the following year. The provisional boundaries used for the 2018 general election were recreated here from the Hamilton County district basefiles to match the chart of precincts and districts in place for that election. Concord 5 has been omitted from the shapefile as it features a nonexistent combination of districts and the area of the prior Concord 5 was effectively replaced by Concord 8. Northwoods 3 which does not have any registered voters is omitted from the 2018 precinct list but is split from Northwoods 2 in the next available shapefile. The Northwoods 2/3 split has been included here in order to avoid crossing the relevant legislative district boundaries. Davidson and Wilson reported absentee votes countywide. Robertson, Union, and Wilson reported provisional votes countywide. These were distributed by candidate to precincts based on their share of the precinct-level reported vote. In Polk County the Cooper Basin/Ducktown and Parksville/Shiloh precincts were merged prior to the November 2018 general election.
