Actually, I think that there are strong arguments to remain, but they have not been articulated well, rather it has all been about preserving the status quo. Sadly, if remain can’t present a solidly positive vision of what our future may look like in a future EU, how can there be any confidence in it being delivered by same.
Also, whilst I don’t personally have any issue with remainers, many do seem to be still consumed with patronising outrage that those they consider to be their inferiors: old provincial Tory voters and working class whites, defeated them on a matter that was a core pillar of their progressive culture...
Presenting a solidly positive vision is easy, being accurate isn't. Populists are happy to promise the earth, confident in the knowledge that it doesn't matter if they've won, they can blame others, (Remain n this case) should their fantasies prove undeliverable.
I think it's the Leave side who keep on bringing up your latter points, another similarity with their SNP analogues in Scotland, grievance manufacturing and mining. Always good for votes, that's what the Facebook dark ads were about.
One thing that seems to be happening (if you read some of the editorials) is that there is a shift in British politics. It is ongoing and I don't think anyone is sure where it is shifting to and how far!?
Those that live in the Westminster bubble are finding it hard to understand just what is making the UK population tick. Further evidence if any was needed that good politicians will have had a career in "civvy street" before joining up.
I don't know where we are headed but in the long run all this bollox may turn out to have a positive side.
I think the existing parties are assuming normal jogging will resume in a few years time when the memory of Brexit has faded. The problem with that thinking is that a lot of voters voted out of habit: "I've always voted Labour/Conservative/Limp Dem, so I'll vote that way again".
We have at least two elections coming up where there will be significant protest votes - the local elections and the European elections. We may also see a protest vote in the local elections next year. I think the act of casting a protest vote will jolt some of the electorate out of their ingrained voting habits and make them consider if they should vote for an alternative party in future elections.
As such, I think elections are going to be a lot more fluid in the future - and the established parties would be unwise to take their less attached voters for granted.
