Interesting that the more educated you are, the more likely to vote Labour and the less educated you are, the more likely you are to vote Tory. Notice that the highest Labour voting bloc were those that have finished University and not those IN University. I'd argue that many people who went to Uni understand the social and economic good that it brings to the country as a whole and are willing to sacrifice a small amount of their taxes to ensure access to higher education is as low cost and free as possible.
In all seriousness though going to university doesn't mean you're more intelligent or informed. My mate doesn't vote and couldn't even tell you one difference between Corbyn and May, he got a 2:2 in events management. My housemate is slightly less knowledgeable than the rest of my mates and he went to university too.
I like to think of myself as more informed than both and I chose to leave education earlier as I got a good job offer.
I know the data is more in general terms but I don't think it says much.
