Twin Falls County is expected to file a legal challenge contesting the redrawing of Idaho's political boundaries. County Prosecutor Grant Loebs told the Times-News on Tuesday that local government officials plan to file a challenge with the Idaho Supreme Court over the redistricting maps drawn up earlier this month. The plan laying out Idaho's 35 legislative districts has been a sore spot for some Twin Falls County officials, who fear it weakens their influence. The map splits the county into three legislative districts. The city of Twin Falls would be in its own district, while the rural parts of the county would be split into two other districts that will be grouped with Elmore and Owyhee Counties to the west, and Cassia and Power Counties to the east.
