While Mitt Romney goes stumping for votes in Northern Virginia Thursday, he’ll also appeal to coal-producing areas of the state with a new television ad.

In the space of 30 seconds, the ad twice shows a video snippet of Obama saying, “If somebody wants to build a coal-fired plant, they can. It’s just that it will bankrupt them.”

Titled “Bankrupt,” the ad wraps up with: “Mr. President, let us keep our jobs. We can’t afford four more years.”

Coal has emerged as an important issue in not only the presidential contest, but the U.S. Senate race between former governors George Allen (R) and Timothy M. Kaine (D).
