I WORK in West Virginia, Virginia, Kentucky, Colorado, Utah, Illinois and Wyoming. Other than Wyoming, Colorado and Utah the miners are definately voting Democrat. The states might have voted Red as you stated but the miners have too much history tied to the union and their ancestors.
Even the unions that infest USPS have more Republican voters than you can imagine ~ the only reason the Dems get an edge is that African-American APWU members vote "black", and at the moment "black" is with the Dems.
