Sanders won Idaho by a four-to-one margin over Hillary Clinton, a similarly large landslide win to that of
Barack Obama over Clinton in the Idaho caucuses
eight years prior. In a majority
white,
rural, and ideologically
libertarian electorate, Sanders had the upper hand. He won all counties but one on election day, carrying the major cities of
Boise in
Ada County,
Pocatello in
Bannock County, and
Idaho Falls in
Bonneville County. He was also bolstered by rural support from
Southern Idaho to the
Northern Panhandle, and in
Central Idaho including
Treasure Valley. Such regions are among the most remote and radically
conservative areas of the country. The
Ada County caucus, held at
CenturyLink Arena, which was the largest caucus in U.S. history, easily broke the
2008 record, with many voters waiting in line for three or four hours in brisk
wind chill. The mile-long line stretched for several city blocks; more than 9,100 voters participated in what was called a "massive" turnout, ==References==
