The Remain side won’t even be able to accuse the sceptics of racism: Vote Out balances its demand for a return to national control of immigration with a call to allow more scientists from outside Europe to be allowed to move to the UK. These messages, when they eventually begin to filter through, will resonate strongly with younger people and Londoners, the two groups that tell pollsters they are most likely to vote to stay in. Several other factors will give the Outers a boost. The referendum is likely to coincide with the usual period of midterm blues that affects all governments. Many voters, including some who backed Mr Cameron in May, will want to use the opportunity to give the Government a good kicking, safe in the knowledge that they can do this without handing Jeremy Corbyn the keys to power.
