In the case of this particularly jarring super PAC ad, it may also be relevant that Soptic’s wife died in 2006, years after the GST factory closed down.

A 2006 story in the Kansas City Star reported the death of Ranae Soptic, a former champion roller skater: “Soptic went to the hospital for pneumonia, but doctors found signs of very advanced cancer, and she died two weeks later on June 22.”

I asked Priorities USA strategist Bill Burton to explain the connection between Romney, Bain and a cancer fatality that happened near the end of Romney’s tenure as governor of Massachusetts. The lapse in time between the plant closing and Soptic’s death doesn’t mean the ad is invalid, but it raises questions about the cause and effect relationship here.

“We’re illustrating how long it took for communities and individuals to recover from the closing of these businesses,” Burton responded. “Families and individuals had to find new jobs, new sources of health insurance and a way to make up for the pensions they lost. Mitt Romney has had an enduring impact on the lives of thousands of men and women and for many of them, that impact has been devastating.”
