Joni Ernst, a Republican U.S. Senate candidate in Iowa, has a new ad on making big spenders "squeal" in Washington, D.C.

Ernst's ad notes that she grew up castrating hogs on a farm in Iowa, so she'll know how to "cut pork" in Washington.

The 30-second video calls for cutting wasteful spending, balancing the budget and repealing Obamacare.

Iowa's GOP Senate primary — for the seat that Tom Harkin is leaving — lacks a clear frontrunner, per the Des Moines Register.
