So much writing on the "trivial" that it reveals itself not to be trivial at all, no?
But here's the deal: the hypocrisy issue is only a (wonderful) sideshow. Yes, yes, Sarah is presented as "middle class" and then draped in luxury, whatever. It's "My Fair Lady" gone hilariously awry, etc.
But there's a real reason why this story is such a resonant metaphor for the GOP. When you give Republicans your money (campaign contributions, taxes), they immediately give it to rich people (Neiman Marcus, Goldman Sachs) for short-term gains which benefit only themselves. And then it turns out to be a bad idea. Fiscal responsibility, anybody?
