“To the liberals, she sells her soul — the same ones who hate Kentucky coal," Rand said of Grimes, who has sought to distance herself from President Obama's carbon pollution regulations on existing power plants.

Paul delivered his poem to thousands at Kentucky's Fancy Farm picnic on Saturday.

“So she flew to L.A. for a Hollywood bash. She came home in a flash with buckets of cash," Rand said. “To liberals, she whispers: Coal makes you sick. In Kentucky, she claims coal makes us tick.

The battle over the administration's climate policies, specifically the Environmental Protection Agency's proposed rule on carbon pollution, has dominated the Kentucky Senate race.
