In this sparsely populated swath of eastern Kentucky, it is voters like Watts who have become the prize in what has become a battleground area in one of the country's most watched U.S. Senate races. McConnell, a 30-year incumbent, has tried to tie challenger Alison Lundergan Grimes to Democratic President Barack Obama and what Republicans have called his "war on coal." With most polls showing a close race, McConnell started a three-day bus tour Monday through eastern Kentucky to make his pitch to miners and their families with a little over two weeks left before the election. The tour will take him through 15 counties where the median household income is $33,023 per year, about $20,000 less than the national figure. McConnell has pledged that if he is re-elected he would slash the budget of the Environmental Protection Agency, which has issued a series of new emission standards that state officials say would prevent the replacement of the state's aging fleet of coal fired power plants that, right now, provide about 90 percent of the state's electricity.
