Peggy Noonan has "topped" her WSJ column with an explanation:

When the segment was over and MSNBC was in commercial, Todd, Murphy and I continued our conversation, talking about the Palin choice overall. We were speaking informally, with some passion -- and into live mics. An audio tape of that conversation was sent, how or by whom I don't know, onto the internet.

In our off-air conversation, I got on the subject of the leaders of the Republican party assuming, now, that whatever the base of the Republican party thinks is what America thinks. I made the case that this is no longer true, that party leaders seem to me stuck in the assumptions of 1988 and 1994, the assumptions that reigned when they were young and coming up. "The first lesson they learned is the one they remember," I said to Todd -- and I'm pretty certain that is a direct quote. But, I argued, that's over, those assumptions are yesterday, the party can no longer assume that its base is utterly in line with the thinking of the American people. And when I said, "It's over!" -- and I said it more than once -- that is what I was referring to.
