No matter how good a salesman is, he can't sell something that is thought of and recognized as a piece of shit, and that's what harness racing is to the general public.
Many reasons for this, not the least of which is the betting scandals and the rampant cheating/juicing.
This is what happens when a sport has ZERO policing/regulation and penalties that actually stick.
You can get caught this afternoon and it will take a year or more to be penalized with all of the stays and appeals.
In that time, you can cheat your way to some financial security and can then sit out any penalty.
This isn't "3 strikes and you're out," it's "unlimited strikes" and maybe a little butt cheek spanking.
