Half a century ago, the Left appealed mostly to the poor and uneducated, and the Right to the rich and educated.

Nowadays, supporting leftist parties still correlates with lower income (and supporting the Right with higher income), although that link has weakened.

What’s most interesting is that correlation along the “education” axis has reversed: today, it is mostly educated people supporting the Left, and uneducated people supporting the Right.
