UPDATE: Turns out the woman died five years after the bankruptcy and seven years after Romney left Bain Capital. She also had her own insurance for a year after the bankruptcy, before losing it when she left her own job. Even a NY Times columnist says the ad is "preposterous".

This has garnered lots of publicity. I report you decide.
