In the one-minute radio ad, which began running on July 16 in 35 coal producing counties in the state, outlines the political issue Obama has made of coal and the impact that is having.

“Coal is one of the economic engines of our state,” McConnell said in the ad.

“In some parts of the commonwealth, coal is a proud way of life that binds together generations.

“But President Obama and his allies view coal as a threat to their liberal ideology and green energy policies cooked up in Washington.”

Targeting an early radio ad in the coalfields shows that McConnell isn't taking the mining region for granted. He is spending "in the low five figures" to run the radio ad there for a week.

The Republican will be running against Democratic secretary of state Alison Lundergan Grimes in the 2014 election.
