As Boise's mayoral elections are nonpartisan, neither party nominated a candidate. A total of seven candidates appeared on the ballot. The race featured two candidates who had been mayors of Boise: the incumbent mayor, and 1993-2003 mayor Brent Coles. Incumbent mayor Bieter emphasized that his goals for a fifth term included ensuring access to affordable housing, making Boise carbon-neutral by 2035, and building the new library, while "making sure the project is completed within the budget set by the city". Coles campaigned on his record as mayor, including the consolidation of the city's transport system and his expansion of the police department.
Boise State Public Radio described the race as much closer than usual, and quoted
College of Idaho professor Jasper LiCalzi, who argued that the candidates defied the typical categorization of "a typical Republican and a typical Democrat and a few fringe people", positing that there were "three significant campaigns" vying for votes, which made a runoff election, in the event that no candidate yields more than 50 percent of the vote, more likely than usual. Bieter and McLean advanced to a runoff mayoral election, the first in Boise since 1965, when
Jay S. Amyx defeated
Eugene W. Shellworth. In 2006, the city abolished runoff elections for
City Council seats, but maintained runoff elections for mayoral races. McLean won the runoff by a landslide, defeating Bieter by over 31%. == Results ==
