At least, according to Ace:

Barack Obama isn’t merely destroying his own unearned reputation for smarts; he’s adding to Sarah Palin’s day by day. The public is beginning to wonder if Obama really was as prepared and brilliant as he press swore; and if they’re wondering about that, they must also be wondering about other claims the press swore to, such as the lack of preparation and weakness of mind of Sarah Palin.

Or, as he put it in the title of his post:

Wow, We Really Dodged a Bullet with Sarah Palin, Huh?
