The European left is in a bit of a crisis. The Right sold out their ideology decades ago, but the left is still not used to it.
What was the 'ideology' of the European Right? Monarchism? What about the left throwing out communism?
The mainstream left was never Communist. The split between commies and social democrats occurred before democratic elections were held in most countries.
I was being a bit hyperbolic, but the European right lost many of its major battles (including monarchy in many places, but more importantly stuff like the welfare state and so on). They have tended to adapt and go pragmatic.
The European left is still having a bit of trouble with that. Too much idealism still floating around.
