The opening hearings on the Ukraine scandal demonstrated that mundane government processes and seemingly colorless bureaucrats are what keep our country going. It was these sorts of unknown public servants who maintained the executive branch functioning during Watergate — and are doing so now while our distracted president and his acolytes try to circumvent the rules…
