Not as simple as that, Doug. The Labour Party has moved to the right, and lost support in the process. The Tories have moved leftwards, at least in rhetoric) which is all that matters for an opposition party can, so that there's nothing to choose between the two, and that has helped them gain credibility. The Scot Nats are well to the left of either, so this Glasgow election is in no way a move to the right.

And all of them, Labour, Tories or Scot Nats, are what you would be likely to denounce as far left liberals if they were in the States. (Which would also, of course, be true of Merkel and Sarkozy.)
