People naturally back what they know. I think many people will have a niggling doubt at the back of their mind that will lead them to vote remain on the day. Still I think the actual vote is going to hinge on who turns out on the day. The better educated are tending to vote remain and they tend to turn out, rather than the less educated who are generally for leave. Somewhat diluting this is the grey vote which seems to be towards getting out. Whilst I think we will vote to stay in it'll be close, I can't see it being much more than 5% either way.
