Power 106 has always been a CHR station. Always. Always. They aim primarily at Latino listeners because they dominate LA. I'm not sure who their "P2" listener target was in the past; I have a feeling it was African-American with Caucasian close behind.
When they started, they played primarily dance to get the Latino listener. When that faded, they went more hip hop. But except for a small period in their history, they've always played the biggest crossovers from so-called "mainstream CHR" (I think a mainstream CHR plays what the makeup of the market wants; so mainstream WPGC/Washington was very Urban/rhythmic, mainstream KIIS usually leans rhythmic, etc.). Hip hop has faded, so they're playing what the Latino audience wants to hear. They may not be as passionate about it, but right now it's what's available, unless Power wants to go super recurrent/gold, and they don't want to do that.
Losing a strong Urban doesn't help, but there hasn't really been a strong Urban in LA for 10 years or more. The Beat wasn't very strong in its last years.
