Sarah Palin, says David Frum, "quit to cash in. Her admirers can excuse anything, but to the much larger audience of non-admirers, Palin will look a lot like those CEOs who wrecked their banks and the national economy while accepting huge bonuses for themselves personally. John McCain's slogan in 2008 was "Country First." Palin's in 2012? "I seen my opportunities, and I took 'em."

I said when this first came down the pike that it seemed far the most likely conclusion, since the bow-out was so obviously rushed, that Palin was resigning ahead of some big scandal coming down the pike. But I confess that now I'm not so certain of my initial judgment.

Palin of course has tons of scandals. But if a game changer was on the way, one she had to drop out of sight so quickly for, I think we'd have heard something about it by now. And she's hardly dropped out of sight. Not that I'm counting out the possibility by any means. I'm just not so sure.

Maybe it really was just that she suddenly got tired of the accountability thing. Or couldn't wait the eighteen months left on her contract to start shoveling up the dollars.

As I think a number of others have said, I've always thought Palin's character was essentially that of a grifter. And when these folks blow out of town after a con has run its course, it's usually a pretty hasty exit.

So maybe it all makes sense.
