I see where you are coming from by saying the Conservatives are to far right, and that Labour are to far left.
But what is the alternative ? The snag is that the Lid / Dems should be the middle ground, and have previously been, but now they fanny about so much trying to appeal to / sway the conservative voters, the labour voters, the green voters etc, that they are now becoming bogged down, buggering about, and appeal to nobody as the "middle of the ground" party that they try to be. So we are left with a choice at the moment of right wing, or left wing politics.
