Only a fool would think she has a chance.
Only a fool would have said Trump had a chance just a few years ago.
Again, a lot can change and it's way too early to be making definitive statements like that.
Again, I do not think it is likely. But then again it's not likely that any given individual will be President. It's impossible to say, but just as foolish to dismiss the possibility entirely as it is to embrace it. Especially after what happened in 2016, I don't know how anyone could think anything is off the table anymore.
