This is all tentative, since a new law in the making has yet to be passed. It will determine strategies and tactics that may alter the present situation. But then the majority's bill is also tactical, very much a part of the process, just as the Porcellum electoral law was in 2006. However, it is unlikely to greatly alter the weight of the two blocks: a solid rightwing sweep with a fragmented left bleating about local victories in far-flung corners.
I note in passing that Anderson's article on the Cyprus issue was spot-on IMHO and an excellent introduction to the problem. The road of excess leads to the palace of wisdom - William Blake
