LOWERING HIS HANDICAP, NUNN TOO SOON. Suburban Washington's Burning Tree Golf Club is not considered a politically expedient course because of its policy of excluding women. But Senator Sam Nunn has until now preferred working on his golf handicap rather than his electoral one. By resigning last week the Georgia Democrat appeared to be teeing up for a presidential race in 1992. Of course, he can always follow in Lloyd Bentsen's cleats and rejoin his old club if he loses.
