I'm new here so forgive me if this has been posted before.
Grampy Bobby posted one on famous people and it reminded me of this one from chessbase a couple of years ago.
Of the 16 Democrats, 11 played chess, including 9 of the last 10 (only LBJ didn't)
Of the 18 Republicans, 8 played chess, but only 1 of the last 7 (Dwight D Eisenhower)
Seems as the Republican party became more right-winged, interest in the game waned. Most of the chess players were from the earlier years. Nixon, Ford, Reagan, and both Bushes didn't play.
Obama, Clinton, Carter, and Kennedy played.
Draw your own conclusions.
