This, actually, is a much deeper insight than it may appear.
Alec Baldwin: Sarah Palin: Faux Populist.
So, you think Sarah Palin is embarrassed by the crib-notes-on-the-palm incident?
You're kidding, right?
...Palin reads off the palm of her hand because she can't whittle or cast a fly rod or shoot a wild animal while giving a policy speech. (Then again, who knows?) She reads her palm in order to send a message to her anti-Eastern establishment, Obama-hating, OK-You've-Had-Your-Black-President-Experiment, Tea Party types. That message is, "I'm just one person, doing the best I can with what God gave me. Like all y'all out there."
One of the reasons progressives are often flummoxed by the right's obvious hypocrisy, internally inconsistent positions, childish mockery, and lame policy proscriptions, is that progressives mostly fail to see that much of the right as driven more by tribal identity politics than principles and policies. Their goal is to reinforce their "us". They do this via caricature (Kerry's looks so French! We need a commander-in-chief not a law professor!) and demonize others (Obama's palling around with terrorists! And not only that: he's not actually an American!) to draw the distinction clearly and pull themselves closer together.
This tribal identity politics is vastly more important than "deficit reduction", balanced budget, small government, "freedom" (followed by fist pumps), etc. except to the extent it helps define themselves as apart from and beleaguered by The Others. This is part of why the Tea Partiers are actually driving the Republican Party farther away from mainstream America, into their own little corner of non-pragmatic, rightwing nuttery rather toward a larger party.
It produces internal challenges for Democrats because Democrats now occupy three of four quadrants: not only progressive pragmatists and progressive idealists but also conservative pragmatists (Olympia Snowe being, perhaps, the only one left on the national Republican stage). That's a big tent!
