As the Rather/Mapes story broke and then burst into flames, former Texas Lt. Governor Ben Barnes piped up claiming George H.W. Bush had asked him in the early 1970s to wedge his son W into the Texas Air National Guard to avoid Vietnam. I had to remind people that Barnes, an LBJ protege, had been driven from public office in the Sharpestown scandal, a crooked real estate deal that rocked Texas politics in the 1970s.
