Looking through the academic & scientific literature, I came upon something interesting as to "what makes a good political ad." Attack ads from candidates (with candidate self-identification) on broadcast television have a statistically significant, albeit small, persuasive effect on 2-party vote shares and voter turnout. Whereas attack ads generated by Super PACs are significantly less effective at both. This is on a per ad basis. pubsonline.informs.org/doi/e…
