What's the point of voting in Britain right now?

I really enjoyed watching the Intelligence Debates on Bloomberg this morning. The debate in question was whether the two party system was good or bad for America. This two party system debate is something which is also relevant to the UK I feel. Especially since the Lib-Dems have, for the moment at least, become part of the Tory party. But even without that recent development, Britain has basically had two choices when it comes to elections, Conservative or Labour. And over time I feel this has become bad for Britain. Over time I say because in earlier decades the two parties did more or less represent the two sides of Britain. It quite correctly reflected that Britain was divided between left and right. Not so much rich and poor or upper class and lower class because the Conservatives in certain places were known as the working class party for instance. But generally the choice between Tory and Labour was enough for most people. There was enough difference between the two parties to say there was indeed a choice to make. Yet in both parties desire for power they moderated their policies to try and encompass more people and gain more votes. And so as both parties moved towards the centre, by the time we get to the end of the nineties they as good as met in the middle. There was practically no difference between the policies. Which meant when the voters went to the polls in the election last year they were really voting for the personalities involved rather than the policies involved. This was no more apparent than when we had the three political leaders having a live TV debate for the first time. It was more like an X-Factor reality TV contest rather than intense political debate. It wasn't about what they said but rather how they said it. As such Nick Clegg was suddenly a front runner in the election. A man representing a party whose policies were still a mystery but what mattered was he talked a good game. So he was suddenly seen as a front runner. Surely such a situation where policies are secondary to personalities isn't healthy. And again this has simply came about because of the two/three party system. The possible changing of the voting system may help change the dominance of the the two parties in Britain. But even then who else is there to vote for in the UK? What other parties are out there ready to step up to the plate? The British National Party? The UK Independence Party? The Greens? These are parties which are based around one particular issue. They don't appear to be legitimate national parties with real national policies. That's why I feel more than ever before there seems to be no real choice when it comes to voting in the next election. We don't just need a new national third party. But we need a new national fourth, fifth sixth and party and so on. We need good legitimate national parties to spring up and blossom over time. Because if not there is a real possibility this present political personality contest will develop into a nothing more than who has the best hair, voice, jokes, smile, shape. If one of those taking part in the live TV debates was a very popular TV or film star, a stand up comedian or the latest winner of another reality TV contest, those with the real power know it would help their party win the election. The US perhaps has gone there already. And I feel there is a real possibility of that happening here in a couple of elections time. Those in power will say that everyone should vote. It's not just their democratic right but their democratic obligation to do so. But can you really blame people if they don't vote? What's the point when there is no real choice? There is no real choice because there is no real difference between the main political parties. And this is a result of the two/three party system we have in Britain. If it doesn't change then more and more people will be making the choice not to vote at all. Who can blame them?
