My colleagues and I have a new data release over at the Wesleyan Media Project.  See here.  Among the more noteworthy findings for ads aired through September 15: the DNC and RNC–the parties’ formal national organizations–have aired 0 ads (!) in the presidential race thus far.  Pro-Trump outside groups are on the sidelines as well.  Trump, on the other hand, is on TV with ads, more than Romney was for the comparable period in 2012.

More to come as the data come in…
