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.

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.”

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.

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