Pollsters always say what the think the questioner wants to hear, so, that's rubbish and if you talk about democratic what about the result of the referendum?
The only persons who think it will be disastrous are those who don't want to leave the womb of Angela Merkel and friends.
There is not such thing as a soft brexit that would have financial and legal ramifications attached.
I've yet to hear a convincing reason why UK gets polls wrong when just about every other country gets them right.
At the French presidential election the polls closed and there was an exit poll out seconds later. Everyone treated this as the result. I assume there will be an exit poll on Sunday's election in Italy, and I assume it will be within 3%, even spot on.
In the UK in the hours after the poll closes we discuss whether the exit poll was correct, and we would consider it an achievement if the poll was within 3%. There wasn't an official Brexit referendum exit poll, but the finance industry did its own unofficial one and was out by 4%. Our 2015 election had a wrong exit poll. The 2017 election had a right exit poll, but after weeks of polls that were not consistent one with another, and not ultimately reflected in the vote. Right now polls are not being replicated in local government by-elections.
I don't know what value can be placed in Brexit polls. The results are not all that clear - if anything they seem to be saying not much change. I guess the point is that only a referendum can establish a view at a date. And there is a fundamental democratic breach if a nation keeps having a poll until it gets the answer its political class want.
