Education was the single biggest indicator of voting intention in the EU referendum. Without a leave result, this snap election would not have happened and this the country would be in a stronger and more stable position.
Firstly you refer to this general election and secondly you're got a rather obvious confounder there in the form of age. I can see your point if you're referring to the EU referendum not being won meaning this general election not being held (I was assuming you were refering to support for the tories) but even then my second point is relevant in that case.
