This one will make the Golden Ellipse list in 2010 for Worst Metaphor, because I really have no idea what Mallard is talking about.
What does Congress sell that no one wants...but then give to other people? The Military? Social Security? Medicare?
I'm sure he's probably referring to "wasteful spending", but I think President Obama put it best when discussing it with Republicans (emphasis mine):
"I think one thing that, you know, you have to acknowledge...that the earmarks problem is not unique to one party, and you end up getting a lot of pushback when you start going after specific projects of any one of you in your districts, because wasteful spending is usually spent somehow outside of your district. Have you noticed that? The spending in your district tends to seem pretty sensible."
