For its fans, Small Town America is the heart of the country. It is the rose-tinted paintings of Norman Rockwell, neighbour helping neighbour, the farmer working hard by day and relaxing by night on his porch with family around him and Jesus at his shoulder. It is also the original article: Small towns were the first settlements, and, in the minds of millions, they resemble, more than the corrupted cities, the solid values of the first settlers.
"I guess a small-town mayor is sort of like a 'community organiser'" she said, with a dig at Mr Obama's previous occupation. "Except that you have actual responsibilities."
Beyond talk of the economy, of health care, Iraq or global warming, this election is now set to be a replay of the Clinton-Obama primary battle earlier this year: Mr Obama representing the city dwellers, Mr McCain – egged on by Mrs Palin – the God-fearing, duck-hunting, hard-working countryside.
Mrs Palin has given what was a demoralised party a narrative they can run with: It is a narrative that says troubled times are the best times to return to the honest and simple values of hunting, fishing, hard work and Jesus.
Well, I was born in a small town
And I live in a small town
Probably die in a small town
Oh, those small communities
All my friends are so small town
My parents live in the same small town
My job is so small town
Provides little opportunity
Educated in a small town
Taught the fear of Jesus in a small town
Used to daydream in that small town
Another boring romantic, that's me
But I've seen it all in a small town
Had myself a ball in a small town
Married an L.A. doll and brought her to this small town
Now she's small town just like me
No, I cannot forget where it is that I come from
I cannot forget the people who love me
Yeah, I can be myself here in this small town
And people let me be just what I want to be
Got nothing against a big town
Still hayseed enough to say
Look who's in the big town
But my bed is in a small town
Oh, and that's good enough for me
