Blaine County, Idaho

Blaine County is a county in the U.S. state of Idaho. As of the 2020 United States Census, the population was 24,272. The county seat and largest city is Hailey. It is also home to the Sun Valley ski resort, adjacent to Ketchum.

Blaine County was created by the territorial legislature on March 5, 1895, by combining Alturas and Logan counties; it was named for former congressman and 1884 Republican presidential nominee James G. Blaine. Its present boundaries were set on February 8, 1917, when a western portion was partitioned off to form Camas County.

Blaine County is part of the Hailey, ID Micropolitan Statistical Area.

History

The Wood River Valley in present-day Blaine County was organized as part of Alturas County by the Idaho Territorial Legislature in 1864. By the 1880s the valley supported a thriving mining commerce; in 1882 the county seat of Alturas County was moved from Rocky Bar in present-day Elmore County to Hailey, in response to a population shift from Rocky Bar – which would eventually become a ghost town – to the Wood River Valley.

The Blaine County boundaries described in its 1895 creation ordinance contained lands that soon were partitioned off to form other counties. Only thirteen days after the official formation date of Blaine, Lincoln County was formed from the county. Lincoln itself was later partitioned to create Gooding (1913), Minidoka (1913), and Jerome (1919) counties. Blaine County was further reduced in 1917 when Camas County was formed.

The strong mining economy of the 1880s had substantially declined by 1890, when Idaho Territory became a state. The county began to recast itself as a tourism destination in 1936 with the opening of the Sun Valley resort, originally owned by the Union Pacific Railroad. The area soon attracted celebrity visitors, and later residents, most notably Ernest Hemingway, who is buried in the Ketchum Cemetery. Celebrities who have lived in Blaine County include Adam West, Demi Moore, and John Kerry.

County profile

Most Blaine County residents live in the Wood River Valley along State Highway 75 in the western half of the county. This area includes all of the county's incorporated cities and towns except Carey, which is located in the south-central part of the county at the junction of US 20 with US 26/ 93. The county's gerrymandered southeastern panhandle, known locally as the Yale area, is sparsely populated.

As the home of a major ski resort, Blaine County has a higher cost of living than surrounding areas; the median value of its owner-occupied housing units is more than double the state average. As a result, many who work in Blaine County live in outlying areas, particularly in the city of Shoshone in neighboring Lincoln County. It is estimated that 2,540 people from outside the county commute to work in Blaine County.

Government and politics

Since 1992, Blaine County has gained a reputation as a Democratic Party enclave in strongly Republican Idaho. The Democratic presidential candidate has won the county in every election since; that year, incumbent George H. W. Bush finished third behind Bill Clinton and Ross Perot. In 2000 and 2004, Blaine was the only Idaho county carried by Al Gore and John Kerry, respectively. Barack Obama carried the county in 2008 by a 33.2% margin over John McCain, while McCain won statewide by a 25.3% margin. It was one of three counties (Latah, Teton) in Idaho won by Obama in 2008, and by far the highest margin. In 2020, Joe Biden defeated incumbent Donald Trump in the county by 36.8 percentage points, with his 67.1% vote share being the highest for any Democrat since 1900.

Obama also carried Blaine County in 2012 with 58.8 percent of the vote, compared to Mitt Romney's 38.7 percent. Blaine County was the only Idaho county in which Obama received over 50 percent of the vote, although he also carried Latah County with 49.6 percent of the vote. From 1968 through 1988, a less populated Blaine County was won by the Republican candidate in all six presidential elections, as was the state of Idaho, although even then the county voted more Democratic than Idaho as a whole in every election going back to 1924.

Similar to other Idaho counties, an elected three-member county commission heads the county government. Other elected officials include clerk, treasurer, sheriff, assessor, and prosecutor.

In 2006, Blaine County voted 66.3% against HJR 2, which amended the Idaho Constitution to outlaw same-sex marriage in Idaho; the measure passed with 63.4% of the statewide vote. Latah County, (Moscow, home of the University of Idaho), was the only other county where the measure failed.

At the state level, Blaine County is located in Legislative District 25, which currently has an all-Democratic delegation in the Idaho Legislature. Michelle Stennett, the current minority leader of the Idaho Senate, and Wendy Jaquet, a member of the Idaho House of Representatives and a former minority leader of that body, both live in Ketchum.
