The mood in the EU is that after Hungary, we don't need Eurosceptic nations polluting the Union from the inside. There'd have to be a groundswell movement far larger than the original Brexit movement, and I simply don't see that happening.
The fundamental issues of why Brexit happened have to be addressed first, and the British people simply don't want that.
Examples: 'We get our special deals back'. That was negotiated from inside the EU, with the leverage to leave or abuse the veto they held. That leverage is gone.
'We won't join the Euro'. That was a special opt out, also negotiated from inside the EU.
Of course Britain wants to have its cake and eat it. We all do, but it's about leverage, and the UK has exhausted its leverage. Better that the EU and UK remain close allies but forge different paths. It's clear the UK doesn't want to pay the cost of EU membership.
It doesn't really matter what the bulk of British people think they want if the elites can spend a few million turning swing voters against their own interests, and that's fundamentally what needs to be addressed.
