Results of the 1998 Senate election in Wisconsin, shaded by margin of victory. At the beginning of 2000 the border between Jackson and Monroe counties was adjusted to more closely follow the Black River. This version of the map uses the old border that was in effect in 1998.
Based on the version from 1 December 2022 of File:2000_United_States_Senate_election_in_Wisconsin_results_map_by_county.svg. New county lines informed by The Newberry Library. County winners based on the Wisconsin Blue Book.
