Are you a Northern Californian going to Nevada, Colorado, New Mexico, etc. to campaign for Barack? If so, I've got some yard signs for you to take with you. Email me. They're hard to come by, don't you know.
I know you want them. And you can have all I've got.
To everyone else, let me direct your attention to the magnificent piece by Sean Quinn on fivethirtyeight about why you cannot get a yard sign. There's a reason.
Don't worry about your sign. Go walk a precinct. Here's a little contest. First person who emails me with some kind of photographic proof that they walked a precinct in a swing state (preferably Virginia) gets a black HOPE T-shirt. And a book. And a yard sign.
