Politicians think about immigration differently from the rest of the population. For some people that difference will be easily explained – something along the lines of politicians preferring to ignore immigration, but the rest of us having to live with it. Actually, the reverse is the case. The truth is that politicians worry about immigration more than the rest of the population do, not less. That’s because politicians take polls seriously, and the polls say that immigration is the second most important issue “facing the country”. Tracker polls by YouGov regularly show this: the latest has the top three issues as the economy (82%), immigration (47%) and health (25%).
