On Monday's broadcast of "CNN Primetime," Rep. Annie Kuster (D-NH) discussed a potential presidential run by Sen. Joe Manchin (D-WV) and stated that Manchin "represents West Virginia, a history of coal, a history of carbon pollution, in my view, and I think we're in a transition period." And that Manchin knows carbon pollution has to be decreased and "will be ready to make that transition as well."
