UKip - haven't exactly being following them but as far as I see they are a one policy party - they would take us out of the EU and then what? would you trust them with education, defence, healthcare, crime, economics, environment, civil liberties etc. etc. Oh . . . sorry think they also have a policy on immigration! that's two.
On the question of leaving the EU, they see it in one dimension: saving money for the UK and stopping immigration. No body wants to talk about the fact that the UK is a very, very tiny island that has been punching above its weight for a long time. The world is changing with new more substantial countries taking more important roles, think China, think Russia, the more westernised parts of the Middle East. The e UK's voice will become less significant in years to come unless we are allied with the rest of Europe to give us more influence.
I wont go on about other aspects of politics other than to say that for some time now I have been thinking that 'Party' politics is the problem. We should have a different process of election whereby no one is allowed to vote until they have read and understood the policies and implications of them (instead of the bill boards slogans). I don't really mind which way people vote, but I find it annoying when people vote because of superficial reasons - when I was about 15/16 I and too young to vote I recall a supposedly educated 19years old student who decided they would vote for Tony Blair just because he played guitar with Noel!
Manifestos should be kept simple enough for people on the street to understand - i.e. we are going to slash working tax credit and that means . . . . . . then let people vote on the reality of the policy, not the spin, slogan or personality etc.
