In the 2012 elections, the first election after redistricting in 2011, Democrats gained two seats in Ada County, but Republicans offset those gains by winning a seat in Bannock County and a seat in the district representing the Democratic stronghold Blaine County. In 2014, two Republican incumbents representing swing districts in North Central Idaho lost re-election, but picked up one seat previously held by a Democrat in the same region for net loss for Republicans of one seat.
