Okay, the user sent "power-base". Let me check the translation rules again. The first rule says to translate all content into Portuguese. The second rule states that if the content is already in Portuguese, leave it unchanged. The third rule is to provide only the translation result without explanations.
So, "power-base" is in English. I need to translate it into Portuguese. The direct translation would be "base de poder". Let me confirm if that's the correct term in Portuguese. "Base de poder" is commonly used in political contexts, referring to the foundation or support that gives someone power. There's no indication that the user wants a different term, so "base de poder" should be accurate. I should output only the translation without any additional text.
