As usual, the tired old bigoted comedian Rush Limbaugh took offense that anyone could call Sarah Palin "nuts," even though she is quite obviously a few sandwiches short of a picnic, and her grip on reality is, shall we say, tenuous. And as usual, Limbaugh blamed it on the left, i.e. the Guardian's Wintour/Watt blog. What he doesn't understand is that Palin's nutsiness is not a partisan matter in Britain, or anywhere else in the world. It is an obvious truth marveled at by all. Palin's emergence as a serious figure in American politics has made the country a laughing stock across the world. The idea that a stateswoman like Thatcher, in advanced dementia, would be used by such a crackpot is simply unseemly.
