Scrappleface reports that, while waiting for the inauguration, Barack Obama is working on another memoir. This one will chronicle his days in the Senate.

According to a news release from the publisher, the memoir entitled 143 Days That Shaped a Nation: The Senate Career of Barack Obama, “is third in a series of biennial Obama memoirs and promises a behind-the-scenes look at the inner workings of the senate from an outsider’s perspective, along with personal anecdotes about senate colleagues whom Sen. Obama occasionally met, or heard about.”

“When you have served as long as I have,” said Mr. Obama, “I think you have an obligation to pass on some of that wisdom that comes from your experience for the benefit of the people of the world.”

Illinois Gov. Rod Blagojevich must now choose a replacement who has experience comparable with Sen. Obama’s — a daunting task, the governor said, “when you realize that whomever I pick as junior senator might be just one great speech away from the Democrat presidential nomination.”
