From a reader:

Jonah,
Thanks for clearing things up. I live on Capitol Hill, and every evening when I walk my dog we see a beat up car bearing a Sleater-Kinney bumper sticker (as well as the first Kucinich sticker I’d ever seen). Until today, I assumed the car belonged to a House staffer and that Sleater-Kinney was a piece of legislation, most likely health care.
Murphy the Dog was more correct in his assessment. I suppose I shouldn’t yank him away so quickly…
