Gary Kiehne is a Republican candidate for Congress in Arizona.  And he just sent out a bunch of fliers with the standard talking points..."Washington is broken"..."smaller government"..."repeal Obamacare" ...stuff like that.

There's also a photo of him on a ranch in a cowboy hat, talking with two other guys in cowboy hats next to a pick-up truck.

What he DIDN'T notice was the photo accidentally features a horse with MASSIVE JUNK!

Seriously.  There are three horses in the background eating near a corral, and you can see a GIANT HORSE DONG on one of them.
