I'd agree with that. But I'd also say that one thing that is drilled into you at university is to examine any subject from both sides and look and use fact based conclusions that stand up to scrutiny and questioning. So that is why university students may think they have come to a logical fact based conclusion on which way to vote. And non university educated people did not and relied more on other reasons.
I would not dare endorse or condem that opinion, just saying that is one possible reason.
I take that on board. I still think some of the students will have struggled to study the subject fully, done their degrees, worked part time and enjoyed themselves in the evenings. What with their schedules so busy a large portion couldn't make it to the polls.
I I think it's human that if you have an opinion, no matter how much you read to the counter, your less likely to change it. A subject of study where an answer needs to be deduced is entirely different to cross examining something you believe.
