President Clinton will play in Saturday’s third round of the Humana Challenge. His playing partners will be Greg Norman, former UCLA star Scott McCarron and Humana CEO Mike McCallister. The Clinton effect in this tournament has been real. He got Norman to play in the field, and all sorts of other big names followed, like Phil Mickelson and Dustin Johnson. He participated in a health conference yesterday, and he’ll be a gallery star on Saturday. Presidents are good for golf!
