It has been a tough August for Barack Obama, but it doesn’t seem to be getting any easier. His departure from Washington for a week’s vacation on Martha’s Vineyard was delayed Sunday morning with the arrival of high winds brought by Hurricane Bill. Once he gets to the island, things may not be much better. Officials are expecting nearly 20-foot-high swells and winds around 100 mph. Take note, first family: Massachusetts Governor Deval Patrick said, “Waters may be unsafe even for strong swimmers.” The brunt of the storm should arrive offshore as it makes its way to Nova Scotia this weekend.
