Unwritten rules about the division of labor in campaign advertising dictate that candidates run mostly positive commercials about themselves, while outside groups beat up the opponent. I understand that negative commercials have been effective in many races, but few things are more irritating than cookie-cutter political attack ads. Listening to the radio every day in recent months, the only ads I’ve heard from Democratic-aligned groups such as the Democratic Congressional Campaign Committee, the Democratic Senatorial Campaign Committee, or NextGen Climate Action have been attacks on U.S. Senate nominee Joni Ernst or IA-03 Republican candidate David Young. When the DCCC starts spending money in IA-01, I’ll bet the only ads produced will be attacks on Republican Rod Blum.

Meanwhile, front groups for Republicans have been running a mix of positive and negative ads. In the IA-Sen race, some of the best pro-Ernst ads have come from the U.S. Chamber of Commerce or the National Federation for Independent Business. Similarly, Ernst’s campaign has run a mix of positive radio ads about her and attacks on Bruce Braley, including a vicious one that’s in heavy rotation now statewide.

I believe that the National Republican Congressional Committee’s positive ad featuring Tom Latham’s endorsement of David Young in IA-03 was more effective than the cliched attacks on Democratic candidate Staci Appel.

It’s been months since I saw any positive television ad about Braley, aside for a few spots produced by his own campaign. Earlier this year, Senate Majority PAC ran some ads that painted Braley in a favorable light, but otherwise it’s been non-stop anti-Ernst messaging from that group, the DSCC, NextGen Climate Action, and Sierra Club Political Action. Most of these commercials have been mediocre at best. Even if they were high quality, I don’t think the strategy helps the candidate they are trying to help.

For some reason, Democratic ad consultants don’t seem to understand that Iowans need to hear reasons to vote for Braley as well as reasons not to vote for Ernst. There is radio silence on the pro-Braley front and not much positive about him on television. Meanwhile, Iowa viewers and listeners are hearing reasons to support Ernst as well as reasons not to support Braley. I believe the lack of positive messaging about Braley is a strategic error and a key reason recent polling in the IA-Sen race has shown slightly better favorability numbers for Ernst.
