I would point out, that like all political parties, they get where they get, by people voting for them. Telling them they're idiots to do so, and sitting in holier than thou, I know better than you; judgement on them, changes nothing. It does however incur resentment.
Instead of criticising how people vote, or telling them how they should vote. Why not present them with positive ideas, and good policies?
UKIP is OTT, but it's telling the electorate, what they want to hear.
Most people don't give a flying fuck who runs the banks, or the railways, or the country. What they want is a decent job, at a decent wage, and lower prices for essentials.
The class based hatred and angst that they hear from left and right, is about as important to them, as the price of caviar.
That's one of the main reasons, that so few people vote.
It's all shit, and who can tell the difference between a lump of tory shit, and a lump of labour shit?
