Well, about 15 years ago, Clinton took some Indonesian money, and declared some Utah lands to be federal parklands. It just so happened that Indonesia and Utah happened to have the only two major deposits of some kind of ultra-clean burning coal.
These guys can talk about re-opening those lands, to help the US economy, to help Obama's vision of cleaner-burning coal, and to create jobs. The Left would have a very tough time fighting it, especially if we kept Clinton's corruption as a quiet bargaining chip in the deal.
IIRC, there is one other as clean--in Kosovo. Dog wagging took that out of play nicely.
