A slim majority of those who voted, several years ago, stirred up by masses of illegal propaganda, especially in the last days before the vote. Now after getting some idea of the reality, the tides look to have significantly changed. Current opinion polls are showing significant majority for remain.(61% in the last YouGov poll)
(Also, it was 17 not 33)
That "61%" is probably about right for what would you'd get for a two-way referendum between Remain and No Deal, or between Remain and May's Deal, but if you were to repeat the Remain-Leave referendum (which would be an insane thing to do - it was madness the first time), I wouldn't be surprised if Leave would win again, by a narrow margin.
"Well, if you knows of a better 'ole go to it"?
A) Should we leave?
B) if we leave, should be we leave even without a deal with the EU?
I.e. two (or more) distinct questions. If you vote no at the fort question, you still get to express your opinion on the second.
This is why you do ranked choice voting, which covers any combination of such opinions.
I have found betting odd's to be far superior insight than public opinioin polls and with that, ring up a betting shop and ask them what odds they will give that the UK stays as an EU member, that should give you a fair perspective as unlike polls, any mistake they make costs them money.
But for me and many others, polls are futile and so often very very wrong as Brexit and Trump have demonstrated.
Polls before Brexit where wrong, no reasons to trust them now.
