Say, why doesn't Obama just make Valerie Jarrett Vice President?

Although I suppose that would be a demotion for her. Kind of like the ventriloquist changing places with the dummy.

No one outside Michelle has the access or power over Obama's decision-making like Jarrett does. Here's an odd little fact that gives some insight into what kind of president Obama is: Michelle, Michelle's mother, and Valerie, and only a few others in Washington, are allowed to call Barack by his first name. After work, Jarrett joins Obama at night in the Family Quarters, where she dines often with the First Family. She goes on vacation with them.

Jarrett's title is the weird mouthful "Assistant to the President for Public Engagement and Intergovernmental Affairs." She is the gatekeeper, but she is also much more than that. She occupies Karl Rove's and Hillary's old office and has an all-access pass to meetings. She shows up at the National Security Council, at meetings on the economy and budget. She stays behind to advise Obama on what to think and do. Obama uses her as his left-wing conscience. Klein's sources describe how at each pressing issue, Obama turns to ask her, "What do you think the right thing to do is?" As president, he likes to have her next to him "as the voice of authentic blackness in a White House that is staffed largely by whites."
