If I were to try to draw conclusions (not sure how reliable Lord Ashcroft Polls are), I would say that attitudes toward capitalism (neoliberalism) is a factor that corresponds most closely with the way people cast their ballots.

The others, while certainly significant, may not have as great an overall weight. It also shows how deeply reactionary many of the Leave voters are on social issues and things, such as the Internet, that many simply take for granted as part of contemporary life.
