Don't bet on Rendell joining the cabinet

From NBC's Abby Livingston
For those speculating that Obama will choose Pennsylvania Gov. Ed Rendell to join his cabinet, you might want to think again.

Here's why: If Rendell is appointed, Pennsylvania's lieutenant governor would be sworn in as governor. However, Lt. Gov. Catherine Baker Knoll -- a Democrat -- passed away last week. As a result, the Pennsylvania Senate Pro Tempore Joe Scarnati will ascend to the lieutenant governor's office.

The catch here? Scarnati is a Republican. So Obama picking Rendell would result in a Republican becoming Pennsylvania governor.
