Joni Ernst, a Republican candidate in the GOP Senate primary in Iowa, is touting her experience “castrating hogs on an Iowa farm” to underscore how emphatic she will be about ending pork barrel spending in the U.S. Senate.

“I’m Joni Ernst. I grew up castrating hogs on an Iowa farm. So when I get to Washington, I’ll know how to cut pork,” Ernst says in the ad, followed by the sound of a pig squealing.

The ad, which was provided exclusively to Breitbart News, will appear in television spots in Iowa. Ernst ends the ad saying, “Washington’s full of big spenders. Let’s make them squeal.”

As previously reported at Breitbart, Ernst is one of several conservative candidates who are running against a wealthy businessman with a strikingly liberal record.

Former energy executive Mark Jacobs has expressed support for cap and trade, Common Core, the Ryan-Murray budget compromise, and raising the debt ceiling. He donated to Arlen Specter after Specter switched parties to become a Democrat. And in a new campaign ad he says one of the best things about a strong economy is that it would provide the federal government more tax revenue.

Jacobs early lead in the polls – he’s benefiting both from abundant personal resources as well as a field split across six candidates – has Hawkeye State Conservatives spooked that none of the several credible conservative candidates will emerge as the top Jacobs challenger.

Ernst’s new ad, and her unusual qualifications – for politics, anyways – could help separate her from the pack of conservative challengers to Jacobs.

A state senator, Ernst is in the Iowa Army National Guard and served in Iraq. 

Here’s the script:

Joni Ernst: I’m Joni Ernst. I grew up castrating hogs on an Iowa farm. So when I get to Washington, I’ll know how to cut pork. [Pig squeals.]

Narrator: Joni Ernst. Mother. Soldier. Conservative.

Joni Ernst: My parents taught us to live within our means. It’s time to force Washington to do the same. To cut wasteful spending, repeal Obamacare, and balance the budget.

I’m Joni Ernst and I approve this message because Washington’s full of big spenders. Let’s make them squeal.
