A fascinating look at how negative this presidential campaign is: “In Richmond, a battleground state media market that is seeing some of the heaviest advertising, not a single positive presidential campaign message ran on television from June 9 through June 22, according to Kantar. But attack ads ran 4,504 times.”
Cue the traditional wailing, but I think we can also point the finger at the electorate: if positive ads worked, campaigns would use them more frequently.
