Per this, Barack Obama has selected Virginia governor Tim Kaine to be the new chairman of the Democratic National Committee, replacing Howard Dean. Since Kaine is still in office, he'll be working part-time until January 2010. In early November, when the possibility of him being named was raised by Obama, Kaine said this:

"That's not something I'm going to do... I don't view that, frankly, as consistent with being governor, so I'm going to be governor... I would view it as taking my eye too much off the ball about things that need to happen here."

Not only will Kaine's opponents in Virginia use that and related issues against him, but he should also serve to be useful to the Republican Party on the national level due to the fact that he isn't too very bright; see his name's link above.
