Well, I was sort of right....
Turns out, it's a political ad for Joni Ernst, a Conservative (Republican) from Iowa running for U.S. Senate. And I have to say, I was a bit disappointed.
When Joni said, "I grew up castrating hogs on an Iowa farm, so when I get to Washington, I..." I was SURE she was going to say, "I'm going to castrate some Congressmen!"
Instead, she promises to cut pork.
While there is nothing wrong, in theory, with cutting pork (though pork-barrel spending can be a boon for districts, as it often creates jobs or things helpful to a particular community, which is why Congress men and women favor it), I can't help but think that castrating a few of the pigs in Congress might be more effective.
