Tropical Storm/Hurricane Isaac is strengthening in the Gulf of Mexico and is expected to be a Category 2 storm by the time it hits the coast-- threatening to hit New Orleans almost seven years to the day after Hurricane Katrina devastated the city.
Though the opening day was cut short, the Republican National Convention is expected to go on as planned. Ed Schultz talks to historian Doug Brinkley about what Isaac could mean for Gulf Coast residents and the tone of the RNC.
