Politico: Chairman Jim DeMint?
If Republicans win the Senate, DeMint would grab the gavel of the powerful Senate Commerce, Science and Transportation Committee, giving him oversight over everything from highway funding, to NASA, to Internet regulation. Its a position with the power to shape the national agenda over a wide swath of the economy, and DeMint emphatically says hell be just as uncompromising with a gavel in his hand as he has been in his seven years as a bomb-throwing backbencher.
