The state is divided into 35 districts, each of which elects two representatives to separate seats.

[3] The Idaho House of Representatives has been continuously controlled by the Republican Party since the late 1950s, usually by a wide margin.

In the 2010 elections Republicans won back many of those seats, gaining five.

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.
