Boston University history professor Brendan McConville backs up Sarah Palin's account of Paul Revere...

... but said she got "lucky." 

Is there anyone else in American public life who is treated like Sarah Palin? Here's this historian, forced to say she wasn't wrong — after all the Sarah-haters have mocked her — and he instinctively grasps for a way to knock her down again. If she got something right, it must just have been an accident.

And here's Andrew Sullivan commenting on Palin's refusal to back down on here Revere story:

One of the most pernicious and dangerous features of Palin is her clinical refusal to understand reality, to accept error, to acknowledge when the facts she has cited are not actually facts, but delusions. And her vanity and pathologies are so deep she will insist that black is white until her minions actually find a source to prove it.

She's dangerous; she's shrewd; she's an exhibitionist. But she is also, we must keep reminding ourselves, a farce. What worries me about this political leader incapable of telling fantasy apart from fact is that, in a long and deep recession, someone who can lie that readily and manipulate religious and cultural resentment as well as she does is a danger. Not just to America, but to the world.

We must keep reminding ourselves... isn't that the attitude of someone with a clinical refusal to understand reality, to accept error, to acknowledge when the facts cited are not actually facts, but delusions. You have something you want to believe about Sarah Palin, and whatever new information you receive, you reflexively remind yourself that she is a farce. Applying your own standard, at what point would you be a farce?

In another post, Sullivan says "I fear I'm headed to crazy-land." But he's talking about his beard.
