Yes. I'd suggest it highlights that those more disenfranchised with the system have found a voice and a lever to effect change. It's also providing an indicator that (assuming they remain engaged) the political elites will have continue listening to them in the future. That's a significant shift in societal influence if it can be maintained. That's a big if admittedly.

You'd know that if you'd at least got your Masters. Badumtish!!!

More seriously, the analysis also doesn't preclude higher education and voting leave. It's claiming to have found a trend. And finally, educational attainment isn't always a good indicator of intelligence. Unfortunately it's seems that its often culture that leads to a good education, not ability.
