Pundits need to stop it with this "mock the unsophisticated yokels" click-baiting and trolling.
Of course people are Googling about the EU after a major upset referendum about the EU.
One reason "insane" anti-establishment positions like this are winning (even when they are insane) is because pundits stubbornly refuse to actually listen to peoples' reasons for supporting them. Instead they mock them as backwater idiots and insult their intelligence.
I don't know UK politics well enough to say for certain, but I know in the USA Trump is largely a FU vote against an establishment that's allowing vast swaths of the country to collapse into permanent depression while ignoring the problem and horribly distorting the economy to keep Wall St. pumped up at the expense of things like housing affordability. I can't stand him myself but I know where the support is coming from, and if nobody listens to these issues we're going to have President Trump in November.
