That is precisely why UKIP are making gains - All the big three parties were resting on their laurels, and now that a threat has emerged, they are running around like headless chickens. UKIP has exposed the fact that, despite the big three championing a "Reconnect with the people of Britain" line, they clearly don't actually know or really care, at least until it actually affects them.
What compounds the issue further for them, is that they've spouted the same lines they did after the Euro elections, and they clearly haven't heeded that particular "Wake-up call".
