http://news.yahoo.com/s/ap/20080419/ap_on_el_pr/democrats_coal_4;_ylt=ArEzWPgpqgVWgWeGNWdZshRrAlMAWASHINGTON - Democrats Barack Obama and Hillary Clinton are walking a delicate line as they promise to aggressively tackle global warming while trying to assure voters that they continue to believe in the future of coal.
In states like Pennsylvania, where voters will cast ballots this Tuesday, and in West Virginia, Kentucky, Indiana and Montana — upcoming primary states — coal sways voters.
While increased mechanization has produced a dramatic decline in coal industry employment, the numbers remain substantial. There are 47,000 coal workers in Pennsylvania and West Virginia and 21,000 in Kentucky, according to the National Mining Association. The three states are the country's biggest coal producers after Wyoming.
Both Obama and Clinton have rallied environmentalists with their promises to develop windmills, solar power and other renewable energy sources and order mandatory reductions in greenhouse gases from power plants to counter global warming.
