How nasty were TV ads in Nevada?

Source: Center for Public Integrity analysis of data from Kantar Media/CMAG covering TV ads aired between Jan. 1, 2015, and Feb. 22, 2016.

Note: Kantar Media/CMAG tracks ads on broadcast television and national — but not local — cable. Figures include those sponsored by candidates' own campaigns as well as supportive super PACs and nonprofit groups. Negative ad total includes spots that contrast multiple candidates and typically cast at least one in a disparaging light.
