Any Iowans who don’t already know that Representative Bruce Braley disparaged Senator Chuck Grassley at a fundraiser will likely hear about it very soon. Priorities for Iowa announced yesterday that it is spending $250,000 to run a television ad statewide featuring Braley’s remarks. Click through to watch the 30-second commercial. Priorities for Iowa was formed by supporters of Joni Ernst for U.S. Senate. We’ll probably never know who put up a quarter of a million dollars to run their ad, since 501(c)4 groups can keep their donors’ identities secret.

Meanwhile, rival GOP Senate candidate Mark Jacobs just launched a new 60-second radio ad featuring Braley’s comments. Click through to listen.

Lacking the money for paid advertising at this point, the other Republican contenders in the IA-Sen primary have to settle for condemning Braley in social media posts and e-mail blasts to supporters.

Braley’s staff got a couple of reminders yesterday that they need to raise their game. The Des Moines Register’s Jennifer Jacobs dinged the campaign for misspelling the words “baling” and “detasseling” in a press release defending the Democratic candidate’s record on agricultural issues. (For what it’s worth, my spell-checker marked the correct spelling of “detasseling” in red.) Buzzfeed’s Andrew Kaczynski noticed that a stock photo accompanying a Braley Facebook post was of a farm in England, not Iowa.
