UKIP voters are so disaffected, and so distrusting of politicians, they cannot easily be 'bought off' by policy offers. There are also more limits than there used to be on the capacity of mainstream parties to respond to these concerns over Europe and immigration. The radical actions demanded by these voters come with large risks and large costs, and are opposed by many other voters as well as significant organised interests, like the business community. Policy-makers face the difficult task of having to balance these demands, but the compromises that result do not satisfy the radical right electorate. Meanwhile, politicians are generally unwilling to explain to voters that they cannot have the policies they want. Few people in politics want to admit to being powerless, particularly on issues like immigration and Europe, where many of their constituents have very strong opinions. Therefore, they often make incremental policy shifts and try to sell them as radical reforms. This, however, can backfire dramatically: if already sceptical voters feel they are being hoodwinked, such reforms can reinforce the dissatisfaction and distrust they are designed to address. - Robert Ford and Matthew Goodwin, Revolt on the Right
