Quite the contrary, the genetic base of mustangs is spanish. Sure, just about every kind of horse on the continent has been mixed in and with the exception of a couple of relatively closed populations, they are mutts - that doesn't change the origin. No offense, but the very fact that many mustangs exhibit strong spanish traits clearly demonstrates the continuing strong presence of spanish genetics.
When you see a mustang with obviously strong draft influence, does that draft influence "not matter" because the draft that introduced the influence lived 100 years ago? Of course not...the genetic influence is there whether the draft was the sire or was 6 generations back - otherwise it would not have the phenotype it does...
