Government and politics
The last Democratic candidate for President to win the county was Lyndon B. Johnson in 1964, although subsequent Republican victories have been by smaller margins than those in neighboring counties.
Similar to other Idaho counties, an elected three-member county commission heads the county government. Other elected officials include clerk, treasurer, sheriff, assessor, coroner, and prosecutor.
Like other eastern Idaho counties, Bannock County has a significant Mormon population which strongly tends to vote Republican. However, a substantial trade union presence in the county - as well as the Idaho State University community - often gives Democrats an overall advantage, especially in local races. Bannock County routinely elects more Democrats than Republicans to county-level offices.
At the state level Bannock County is located in Legislative Districts 28 and 29. Democrats currently control two of these six seats in the Idaho Legislature. In 2016, Republicans were able to win House Seat A in District 29.
