They have, it has been an onslaught but I think it is failing in its objectives, at least in the long term. UKIP continues to rise, the rest continue to snide at them, and not listen to large parts of the country. It’s a strange time in UK politics, I think it is quite likely we will have to vote again in the next couple of years.
UKIP has helped push a political consensus on reducing immigration--something that this country has yet to do. The free movement of labor within the EU complicates matters, but there have been reductions of non-EU immigration. It was hilarious to hear Miliband attacking Cameron for not meeting the immigration reduction targets. Who would have ever imagined a Labour leader issuing such a charge? Miliband admitted that Labour made a mistake on the immigration issue. British jobs for British workers resonates with the voters. Scott Walker is following suit linking immigration with job losses and depressed wages. It is a winner politically and scares the Hell out of the political class.
