It's a common metaphor for her in this interview. Here is how she described her decision to accept the vice-presidential nomination:
I answered him yes because I have the confidence in that readiness and knowing that you can't blink, you have to be wired in a way of being so committed to the mission, the mission that we're on, reform of this country and victory in the war, you can't blink.
So I didn't blink then even when asked to run as his running mate.
And here she is on invading Pakistan:
In order to stop Islamic extremists, those terrorists who would seek to destroy America and our allies, we must do whatever it takes and we must not blink, Charlie, in making those tough decisions of where we go and even who we target.
The first thing that comes to mind is that the only people who have trained themselves not to blink when talking to anyone are self-trained pathological liars. We know she has lied multiple times in the past two weeks. In fact, the lies keep on coming. But what else has she lied about, I wonder?
