“The New York City Republican Convention Host Committee recently designated eight Broadway shows as fit to ply convention delegates with free tickets. There is barely a Tony nominee in the bunch. All are nice, safe musicals guaranteed not to offend mainstream American tastes or, for that matter, provoke much thought.

Isn’t there marketing gold to be mined, especially in Democratic New York, by advertising these plays as shows Republicans love to hate?”
