In reply to PanzerHanzler:
there is a bizarre trend on UKC of people thinking that all, or even a large percentage of voters have looked past the front page of the sun/mail/guardian and spend the time to dig up worthwhile information on what a party stands for, what it's policies on a variety of matters is, and what they plan to do to bring about change.
Many don't even look at the front page...they vote as Jim in the pub has explained things, or as their parents have told them to vote.
This has been further twisted due to it being pretty difficult to find any answers anywhere as there seems to be little clear policy or plans available anywhere, the main parties have all be vague on what they plan to do. Even now the headlines are "PM (or other) says change is needed in our relationship with Europe" but there's nothing easily accessible saying what that means. (and remember most people probably quite rightly expect the info to be presented nice and clearly for them by an obvious source, not to have to trawl through dozens of web links, all from people with their own opinion to shout about rather than just facts).
While I very much dislike UKIP at least they've said "we will do x,y,z to satisfy the complaints the common people have", even if they've pandered to the more unpleasant of complaints, fed simplistic solutions etc.
Politics is incredibly murky and unpleasant in recent years. It's no longer working class vs middle/upper class, it's a mass of hate, lies and unclear claims. It's sadly not surprising that UKIP got such a large number of votes.
