From Michael Cooper's NYT Political blog covering McCain-Palin in Grand Rapids, MI, Palin at one point says: “Sometimes my running mate is a bit too humble,’’ she said. “We need to remember who it was who pushed for and supported and risked much for the strategy that is working in Iraq, and that is the surge. He is the one who pushed for it.’’
It is customary for the top of the ticket to refer to the bottom of the ticket as "my running mate" and not the other way round! This was not the first time.
