Continuing the series, here’s another zombie idea: negative advertising “works.” Either by hurting the candidate who is attacked or by turning off voters from the campaign altogether.  The sheer volume of negative ads certainly keeps this zombie living.

As does the terrific string of cliches attached to so much writing about negative ads. Consider this piece. We have effluvia: “tsunami of slime,” “toxic.” Boxing: “win the fight with a knockout punch.” Gore: “expensive and brutal evisceration,” “bloody victory.” And, of course, war, war, war: “ammo,” “counter-offensive,” “sharpening their arrows,” etc. (I am not even one-fifth of the way through the piece.)

As does many examples of campaign reporting that discuss tactics—like negative ads or the micro-targeting of ads—with only vague statements about their effects. Often from people whose very profession involves convincing candidates to pay them to make ads!

And so you get this from a forthcoming New America Foundation event:

Mudslinging isn’t pretty. But research—and conventional wisdom—says negative political ad campaigns work. Indeed, the tone early on in the 2012 contest suggests that accentuating the positive will not be the hallmark of this election cycle. Should that be of concern to us all? Are negative ads corrosive to our political discourse, or are they, in fact, a vital means of informing the electorate? Join us to consider how political messaging has evolved to its current state, as well as its impact on our broader culture. (And yes, we’ll be airing many past and current commercials.)
