I hope John McCain doesn’t throw his slippers at Sarah Palin’s head or get as acerbic as Henry Higgins did with Eliza Doolittle when she did not learn quickly enough. McCain’s Pygmalion has to be careful, because his Galatea might be armed with more than a sharp tongue.

For the first time in American history, we have a “My Fair Lady” moment, as teams of experts bustle around the most famous woman in politics, intensely coaching her for her big moment at the ball  her first unscripted interview here this week with ABC News’s Charlie Gibson.

Eliza, by George, got it and brought off the coup of passing herself off as a Hungarian princess rather than a Covent Garden flower seller. Sarah’s challenge is far tougher, and that’s why she’s pulling the political equivalent of an all-nighter. She doesn’t have to pass herself off as a different class or change her voice or be more highfalutin. The McCain campaign is reveling in its anti-intellectual tenor.

Sarah, who is now so renowned that she is known merely by one name and has a name ID of 90 percent, has to be a Kmart mom who appeals to Kmart moms and dads. She’s already shown that she can shoot the pig, put lipstick on it, bring home the bacon and fry it up in a pan. Now all she has to do is also prove that she can be the leader of the free world on a moment’s notice, and field dress Putin as adeptly as she can a moose.
