So, it's predictable that the shrewd media site the Drudge Report would position and package Hillary's current challenge in panic terms. That particular panic is about the votes of African-Americans in Florida. Here is the article which the Drudge Report links to.
Panic-Hillary represents a pivot from Sick-Hillary. After all, she did make it through the 90-minute debate. The Drudge Report headlined that as a "miracle." But there's not much more which can written on the health issue currently.
The reality is that, given Hillary, she never enters panic territory. More likely she gets very angry that things aren't going the way she had planned. By nature and training as a lawyer, she is too methodical to ever actually panic. At least not the way ordinary mortals do. This is America's Iron Lady.
