Horse race fixers have long used “ringers” to pull off betting coups, but a new kind of ringer -- genetic duplicates cloned from the DNA of yesterday’s champions -- could soon be barreling around a racetrack near you if two Texas horsemen have their way.
And people wonder why the game is dying?
Between that perception and the thoroughbred break down rate I don't know what racing will be left in 20 years.
