Read this, and there will be cake.
The Nation has an open letter to Barack Obama, urging him to relinquish his centrist stance and adopt a progressive agenda. Right now it's up to 18,500 signatures, and they'll be collecting signatures right up until the start of the Democratic convention. They'll deliver the letter to him on the first day.
Go here to read and sign this letter.
And now, the cake:
Hey, I never said there would be good cake.
The letter via. The cake via.
