John Brummett rises to defend work by Lt. Gov. Bill Halter’s staff on research and education about the lottery amendment Halter has advocated. He’s right. It’s legal. Just as it would be legal for members of the land commissioner’s staff to toil on research and education about an initiated act to clear up tax sale procedures. Or for the secretary of state’s staff to work on an act calling for a new state song. Direct advocacy for a measure is the point at which requirements on expense reporting kicks in. And there are further obvious differences between working on public policy and working on elections of partisan political candidates.
