Deletion of Inauguration of Corazon Aquino

Comment: I don't want to invoke  here, but we usually have articles on the inaugurations of U.S. presidents. Is there a relevant notability guideline for such events? Still, I'm leaning towards keep since I know there is some coverage (albeit not necessarily online) of her inauguration and its significance, although I'm withholding !voting until my question about the relevant guideline is answered
