The UK electorate certainly has its faults. As I've often said we get the politicians we deserve and so so many people vote on the basis of either "what's in it for me now" or "they can't be as bad as what we have now"
But the May election went against that, when it came to the polling booths many people voted for what they saw as credible.
As an ardent centrist/floating voter I just don't get this allegation that they are all the same. OK so the days of one side posturing to ditch the NHS and the other to nationalise everything have gone - surely that's good.
The last election was fought on two areas. Welfare and Financial credibility. And while the latter may seem dull it is very important to people whether they have a job and in the end the most credible party won even with a very vindictive line on welfare.
If you really think they were all the same see here:
http://www.bbc.co.uk/news/election/2015/manifesto-guide Corbynism threatens to overturn this. He is a fundamentally dishonest politician with his promises to adopt a whole raft of socialist ideals and still tell people they would be better off. In power he would take us right back to 1978 misery. Worse he is manifestly an ineffective politician, with him at the despatch box the Tories can abandon their more moderate elements and become very vindictive.
