A new Roanoke College poll finds that 56 percent of Virginians think Bob McDonnell should serve prison time for his convictions on public corruption charges. Harry Wilson, Director of the Institute for Policy and Opinion Research, says fewer than a third of those responding felt that the public humiliation is enough punishment. At the same time, the poll found nearly three-quarters of Virginians didn’t think McDonnell’s conduct was unusual for a public official. The former governor and his wife are set to be sentenced in January.
