Former Idaho Governor Dirk Kempthorne Dies at 74

Dirk Kempthorne, the Republican who helped remake Boise’s downtown before rising to the U.S. Senate, the Idaho governorship and the Interior Department, died Friday evening in Boise at 74 after a colon cancer diagnosis last year. His family said he was surrounded by those he loved most.

Kempthorne’s career began in city hall, where he was elected mayor of Boise in 1985 at age 34 and served seven years. He was credited with helping revitalize downtown Boise by securing an agreement to build a convention center, a deal that helped turn the city’s core from gravel parking lots into a more active urban center as Boise became a magnet for outdoor enthusiasts and new arrivals. Former Boise Mayor Brent Coles said Kempthorne’s vision transformed downtown Boise.

From the mayor’s office, Kempthorne moved to Washington and won election as a Republican to the U.S. Senate, serving from January 3, 1993, to January 3, 1999. He then returned to Idaho as the state’s 30th governor, serving from 1999 to 2006. His path through city, state and federal government made him one of the most prominent Idaho Republicans of his era, a politician identified with pragmatic growth and the kind of development-minded conservatism that once had a stronger foothold in Western GOP politics.

Kempthorne’s final federal post came in President George W. Bush’s administration, where he served as the 49th U.S. secretary of the interior from 2006 to 2009. The U.S. Senate confirmed him by voice vote on May 26, 2006. In that role, he oversaw land and resource policy at a moment when Western governors and federal officials were often locked in disputes over development, conservation and access to public lands, a portfolio that fit a politician who had built his career balancing growth with the demands of the West.

Idaho Gov. Brad Little ordered state and U.S. flags lowered to half-staff in Kempthorne’s honor, and they will remain lowered until the day after his memorial service, which had not yet been scheduled. Friends and former colleagues remembered not only his long public career but also his strong memory for names and small personal details, traits that helped define a political style rooted as much in personal contact as in ideology. In Boise and beyond, Kempthorne left behind a governing legacy shaped by city-building, Western land policy and a brand of Republican leadership that has become less common.
