For me, the first two things that came to my mind was:
1) In spite of the narrative of McCain being absolutely super-awesome in answering direct questions, this is not the first time that he couldn't answer a question, and that him being unable to do so made some news.
There was the one where he didn't know what his position on contraceptives was, for example. It started out with a reporter asking "Should U.S. taxpayer money go to places like Africa to fund contraception to prevent AIDS?" and went downhill from there. (Had a link to the actual video, but lost it. Found the story again here
Q: “So no contraception, no counseling on contraception. Just abstinence. Do you think contraceptives help stop the spread of HIV?”
Mr. McCain: (Long pause) “You’ve stumped me.”
Q: “I mean, I think you’d probably agree it probably does help stop it?”
Mr. McCain: (Laughs) “Are we on the Straight Talk express? I’m not informed enough on it. Let me find out. You know, I’m sure I’ve taken a position on it on the past. I have to find out what my position was. Brian, would you find out what my position is on contraception " I’m sure I’m opposed to government spending on it, I’m sure I support the president’s policies on it.”
Q: “But you would agree that condoms do stop the spread of sexually transmitted diseases. Would you say: ‘No, we’re not going to distribute them,’ knowing that?”
Mr. McCain: (Twelve-second pause) “Get me Coburn’s thing, ask Weaver to get me Coburn’s paper that he just gave me in the last couple of days. I’ve never gotten into these issues before.”
I guess I would appreciate the honesty in saying, for example, "Look, I don't remember how I voted on this piece of legislation five years ago... I'd have to go back and look it up".
But questions about what platform you're actually running on? It boggles the mind.
2) It kind of ties in with all those mini-stories that never really made it into the headlines. Like the one about him visiting that supermarket, being a totally regular guy and chatting with folks in the grocery section - wearing $520 black leather Ferragamo shoes
Still don't know what to say about this one, though.
