I've avoided commenting on the ubiquitous YouTube comparisons to similar evocations from John Edwards and Bill Clinton for one reason: the charges of plagiarism in this context are just silly, as they were, quite frankly, when the Clinton campaign made them about Barack Obama.
The news value of the comments come from their common origin, actually. They're generally uttered when the subject recognizes the existential reality that they are mortal and that they could lose whatever contest is ahead of them.
It's kind of the opposite of saying: "I'm going to Disney Land!"
