Barack Obama’s camp takes aim at Romney’s corporate experience with a 2-minute ad out Monday, and as tales of corporate bloodsucking go, this one could have been penned by Bram Stoker. The ad revisits the closure of a plant owned by GST Steel, which was acquired by Romney and Bain Capital and then shut down. “They made as much money off it as they could and they closed it down, they filed for bankruptcy, without any concern for the families or the communities,” says former steelworker Joe Soptic in the ad. “It was like a vampire. They came in and sucked the life out of us.” The campaign has slated the ad to run in the battleground states of Iowa, Ohio, Pennsylvania, Virginia, and Colorado, but declined to comment on the total cost of the ad buy.
