I understand it now. It's all become clear to me. Sarah Palin's VP nomination is an example to the world of the US's meritocracy; whether you've been there centuries, or just arrived, and struggling with the language (as she seems to be), everything's still open, there are no obstacles, you can aim as high as you want.

Canny man, that McCain. He's trying to win the "...English is not my mother tongue vote...", and that's why SP is on the ticket; she's there as living evidence that wherever you hail from, or irrespective of the fact that your English is shaky... third, fourth language that kind of thing... you can still go places. So subtle. Taken me ages to spot this.

What a politician McCain is. She's there to get the immigrant vote.
