William Kristol has a strategy for raising the level our national discourse as the election draws near:

That debate is important. McCain took a risk in choosing Palin. If she does poorly, it will reflect badly on his judgment. If she does well, it will be a shot in the arm for his campaign.

In the debate, Palin has to dispatch quickly any queries about herself, and confidently assert that of course she’s qualified to be vice president. She should spend her time making the case for McCain and, more important, the case against Obama. As one shrewd McCain supporter told me, “Every minute she spends not telling the American people something that makes them less well disposed to Obama is a minute wasted.”

The core case against Obama is pretty simple: he’s too liberal. A few months ago I asked one of McCain’s aides what aspect of Obama’s liberalism they thought they could most effectively exploit. He looked at me as if I were a simpleton, and patiently explained that talking about “conservatism” and “liberalism” was so old-fashioned.

Maybe. But the fact is the only Democrats to win the presidency in the past 40 years — Jimmy Carter and Bill Clinton — distanced themselves from liberal orthodoxy. Obama is, by contrast, a garden-variety liberal. He also has radical associates in his past.

The most famous of these is the Rev. Jeremiah Wright, and I wonder if Obama may have inadvertently set the stage for the McCain team to reintroduce him to the American public. On Saturday, Obama criticized McCain for never using in the debate Friday night the words “middle class.” The Obama campaign even released an advertisement trumpeting McCain’s omission.

The McCain campaign might consider responding by calling attention to Chapter 14 of Obama’s eloquent memoir, “Dreams From My Father.” There Obama quotes from the brochure of Reverend Wright’s church — a passage entitled “A Disavowal of the Pursuit of Middleclassness.”

So when Biden goes on about the middle class on Thursday, Palin might ask Biden when Obama flip-flopped on Middleclassness.

The answer, so it seems, is for McCain and Palin to turn the campaign away from issues that matter towards petty, false and irrelevant matters of "character."  It's one thing third-tier minds such as Kristol says these kinds of things themselves, it's quite another when they advocate others think and act as they do.  The one is just embarrassing, the other is criminal.
