Like most people in Mingo County, West Virginia, Leonard Simpson is a lifelong Democrat. But given a choice between Barack Obama and John McCain in November, the 67-year-old retired coalminer would vote Republican.

"I heard that Obama is a Muslim and his wife's an atheist," said Mr Simpson, drawing on a cigarette outside the fire station in Williamson, a coalmining town of 3,400 people surrounded by lush wooded hillsides.
