What's that got to do with it jimmyt? If you took a shufti at the article, you'd see it's totally non-partisan, as is generally the case in the paper's Science Section, which is where this piece by a Philadelphia professor of mathematics comes from. The point is that the process discussed works just as well in either poltical direction.

Though actually I'd say that the Guardian is pretty middle-of-the-road - it's just that the political spectrum has been so adjusted that middle-of-the-road is counted as left-wing. To some extent that even applies in the UK - and from all I've seen in the US views that in England would fit happily inside the Conservative Party are classed as as "extreme liberalism."

If you drive along constantly turning right (or left) you go round in circles.
