Okay, the user wants me to translate "power-base" into Spanish. Let me think about the correct term here. "Power-base" can refer to the base of a power structure or the foundation of authority. In Spanish, "base de poder" is the direct translation and commonly used term. I should check if there's any context that might change the translation, but since the user didn't provide additional info, "base de poder" is the safest choice. Also, the user mentioned if the content is already in Spanish, leave it as is. Since "power-base" is in English, translating it makes sense. No need for explanations, just the translation. Alright, that's it.
