Ask yourself if this sound familiar from individual commenters on say the BBC that get massively upvoted (and downvoted).
"This an up yours to the 'elites'"
"The people are railing against the establishment."
That's the very definition of a protest vote.
I think your mixing the two issues as the same thing. But massively in the demographics lesser educated people are resorting to this kind of language and that's obvious if you keep you ear to the ground.
Less about the Tory's winning last election but why are people voting UKIP or Green? In their droves parties unlikely to even get a seat. The SNP a traditional labour heart ground is now almost entirely SNP.
People are railing against the establishment, and a lot of language to why people voting for Trump was the same (if you read around, thank God our friend Austintir isn't around). Why are they running from the establishment?
Let not forget Clinton (the establishment candidate) without the help of super-delegates barely won the Democratic nomination.
Corbyn (again anti-establishment even when his party was in government) has massive support in the UK.
And those are the university educated running in those directions.
It's a mixing up of the protest vote and education levels.

It doesn't matter really. Little stressed out over other things right now (outside of global changing event) probably biting a bit more than I should at ever little bit.
