This seems reasonable.
Voters support the idea of holding a second EU referendum by a 16-point margin, according to one of the largest nationwide opinion polls since the Brexit vote.
The ICM survey, conducted as part of a Guardian reporting project, found 47% of people would favour having a final say on Brexit once the terms of the UK’s departure are known, while 34% oppose reopening the question.
That said, the Brits have the same kind of Fox News problem among their old people that we have here. So even knowing the terms and the extent of the damage that Brexit will cause – a slim majority might still vote for it because they are stupid, brainwashed, racists, dolts.
