| Summary/Abstract |
This research offers a post-mortem on political advertising in 2018, providing important context for 2018’s “blue wave.” In a majority of US House of Representatives races, there were more pro-Democratic than pro-Republican ads, including in the most competitive contests. The one theme that united pro-Democratic advertising was health care, which was mentioned in nearly three of every five Democratic ads in the fall campaign. Contrary to the narrative that television is declining, a record number of television ads aired in the 2018 midterms, whereas digital spending still constituted a small percentage of overall advertising spending for most candidate campaigns. Finally, there was a healthy volume of outside-group spending in 2018, with “dark-money” groups increasing their involvement—especially in support of Democratic candidates.

| Summary/Abstract |
Despite the rapid growth of online political advertising, the vast majority of scholarship on political advertising relies exclusively on evidence from candidates’ television advertisements. The relatively low cost of creating and deploying online advertisements and the ability to target online advertisements more precisely may broaden the set of candidates who advertise and allow candidates to craft messages to more narrow audiences than on television. Drawing on data from the newly released Facebook Ad Library API and television data from the Wesleyan Media Project, we find that a much broader set of candidates advertises on Facebook than television, particularly in down-ballot races. We then examine within-candidate variation in the strategic use and content of advertising on television relative to Facebook for all federal, statewide, and state legislative candidates in the 2018 election. Among candidates who use both advertising media, Facebook advertising occurs earlier in the campaign, is less negative, less issue focused, and more partisan than television advertising.
