The best free show on TV

Americans are among the world's foremost contributors to public entertainment. Hollywood churns out movies with ever-higher budgets and spectacular special effects. The television industry produces endless new programs from documentaries to comedies to mysteries to the ubiquitous court-room reality shows. Public spectaculars such as sports, musical extravaganzas and tours of natural wonders abound. However, for me, they pale into insignificance beside the best show on television these days, the American presidential race.
