Novelist Ayelet Waldman has started the organization Books for Barack to raise money for Barack Obama's Presidential campaign (Note: the website actually refers to it as "Books 4 Barack" but I just can't bring myself to use that damn "4"). The idea is that you donate $250 to the campaign and you get a mystery bag of 10 books in a canvas tote with the Books for Barack logo on the bag - though it's been so popular that Waldman has now said she isn't sending out any more bags...and she has raised $40,000 so far! I'm unclear whether all 10 of the books are signed, but the website seems to indicate that they are. Naturally, she is still encouraging people to donate, even if she can't send out any more mystery bags.
Check out the food, children's, and YA authors who have contributed signed books:
Jamie Lee Curtis
Elizabeth Gilbert (I totally considered Eat, Pray, Love a foodie book!)
...to name a few.
Eat, drink, and support grassroots campaigns!
