Since the mid-1980s, the 15th Legislative District -- which includes all of Klickitat County, all of Skamania County, and parts of Yakima County and Clark County -- has been represented exclusively by politicians from Yakima County.

For many years, the district's three representatives in the Washington Legislature have been State Sen. Jim Honeyford (R.-Sunnyside) and State Reps. Bruce Chandler (R.-Granger) and Dan Newhouse (R.-Sunnyside) -- all from Yakima County.
