From today's TP:
In his column this week, Clark Hoyt, the NYT ombudsman, notes a finding by Politico that "Obama" has appeared six times in NYT crossword puzzles since January 2005, while "McCain" hasn't appeared once. Political bias on the part of crosswords editor Will Shortz? Nope. "Obama is a godsend for crossword constructors because the name is short and has three vowels out of five letters," Shortz said. Hoyt notes that "McCain", with its successive c's, is much harder to work with. No pun intended.
