AND here is what a voter told the BBC:

24. There's another lesson or 50 in it, too.

Passion is fine in bed, but in the ballot box perhaps not. In bed, the worst you get is a child, and STD, or a rape charge. In the ballot box, you're usually the person who's screwed for life.

Populism is great when you're in favor of what it wants. But populism is usually pandering to the masses and making them vote on wants that only you can provide. Populism leads to demagoguery, necessarily. You can't always have what you want. And not only do you "not always get what you want," in populist times you very seldom get what you want. You just get what you voted for, and that's a very different and very dangerous thing. It pisses people off, then they tune out or go even more extreme.

Democracy is the worst system ever devised except for all the others. It works fine on simple issues. But there's a reason we have representative democracies. In the Brexit election, people intended to vote for very specific outcomes that won't necessarily follow from what they actually voted for. "A vote for me is a vote for prosperity" isn't a vote for prosperity but a vote for a politician. A vote for exiting the EU isn't a vote for greater prosperity or cultural protection or to show how pissed off you are with the "elite,", it's a vote for leaving the EU.
