Ed Miliband is unresponsive to voter concerns about welfare because his electoral base - a relatively small percentage of the electorate - is dependent on it to get by.
However, he has started to cobble together a position on immigration because the economic interests of that base have endangered by the Blair/Brown opening up of our borders.
Meanwhile, Labour as well as the Conservatives are under threat from UKIP, and John Mann's piece on Labour List today is well worth reading in this regard.
