The expectations for Hillary are really low. Most likely she will do WONDERFULLY, greatly exceeding everyone’s expectations. She has debated dozens of times and never seized out. Plus she wears an earpiece. She is fed her responses. She’s going to look great contrasted with her most recent appearances. Personally I’d love to see a grand mal seizure or her depends fail her, but I think she will hold her own.
Could it be a hearing aid? That would be a more visual and damaging indicator of her [declining] self.
