Would it be so.
Your scenario is based though on a politically engaged and relatively well educated electorate.
Another ten years of the media dripping poison into every ear and education standards being further eroded could well put paid to that.
I have no faith that if we had a vote in a months time that the electorate would vote to rejoin. The buses/Farage et all would be out in force again and would have a similar effect to last time.
I think you are wrong for a number of reasons.
Firstly, it was 52/48 last time; this slim majority was caused principally by the apathy of the under 30s. That won’t happen again. I think any apathy will be more readily attributed to those that voted to leave, given how it’s turned out.
Secondly, the effluxion of time since 2016 means that many of the people who voted to leave have died and have been ‘replaced’ by those that will want to rejoin. I know that people become more conservative as they get older, but I’m not sure that will so readily apply here. Certainly I cannot see many people who voted remain being converted to thinking leaving was a good idea, which is what would have to occur for that maxim to remain the case here.
Thirdly, there is a tendency to characterise everyone as an obdurate leaver or remainer, but the truth is that many (maybe 10%) were highly equivocal and could see the benefits in both arguments. Any shifting pattern in those voters is only going to go one way.
Fourthly, the world, and Europe, was a far more certain place in 2016, and probably emboldened some people to throw the dice of isolationism in a way that they wouldn’t today in a post Covid world. The comfort blanket of the EU, in a Europe at war, would be persuasive to some.
All those factors, combined with the disaster that it‘s proving to be, and the weakening state of the UK economy means a majority vote to retain the status quo is inconceivable, irrespective of the gullible rump to which you refer, some of whom (although certainly not all) won’t be fooled twice.
I would be prepared to put my house deposit, that I’ve been working like a dog for the last three years to save up, on that outcome. Maybe not 60% but definitely a majority.
It’s simple maths.
