Firstly; because Cymru has not yet managed to reclaim its original cenedlaethol (national) message and is stuck being viewed as a party for only Welsh language speakers and not all supporters of Welsh independence though it is in fact very open to English speakers. Secondly; because despite culture and beliefs though many people would like to see an independent Wales they have been convinced (whether you believe it to be correct or incorrect) that Wales would not be financially viable independent and so fear poverty if voting for independence which would be the inevitable result of a Cymru surge. Thirdly; very traditional voting patterns. The population centre of Wales in the south east (including the South Wales Valleys and the three largest cities of Caerdydd (Cardiff) Abertawe (Swansea) and Casnewydd (Newport)) which contains traditional mining and port towns. They gave rise to trade unionism the NHS (through Welshman Aneurin Bevan) and were the real driving force behind the creation of the Labour Party. Hit hard by Margaret Thatcher Conservatives this region votes for Labour in the General Assembly European and Local elections virtually every time en masse as a tradition. They are also mostly English-speaking. There is social stigma around not voting Labour in these areas as it is culturally engrained (Wales is unlike England a heavily Socialist country and to a greater extent than Scotland). Finally; because Wales has not yet got to the point that Scotland is at. Wales was conquered by England earlier fully annexed and suffered colonisation in a way that Scotland didn't. Therefore it takes longer for Wales to reach independence-it does not yet have the levels of devolution that Scotland does and has much closer ties to England such as the English Legal and Judicial System (which is enhanced by a new and growing Welsh Legal System.). Therefore Wales requires more time to build up its nation before pushing for independence.
