And we all know how reliable they are
Seriously though a new vote would be won by remainers imo.
First I think a lot of people like myself who voted leave would boycott a second vote, the referendum was a one off once in a lifetime vote (or so we were told).
Secondly some will be scared by the remainers project fear mark 11, although I think some remainers who believe in democracy and are sick of the way the EU are acting would change their mind.
And third if it was true that the young voted remain then there will be many 16/17 year olds who weren't eligible to vote in 2016 will now have their say. Where as many older voters will have died or will be to Ill to vote now.
