Well alot of the rappers that are bloods and crips don't let their affialiations get in the way of their money, they don't say it in every verse like alot of the norteno rappers.
I don't think it hurts them that much though, them cats got their own fanbases that are way into that stuff and they arent all Nortenos either.
Thing is i can't see cats like woodie, darkroom etc ever becoming national stars cuz their stuff will never appeal to the mainstream crowds
