As soon as Cameron announced the referendum, Farage's power was diminished. The referendum was what he had fought for. Now he had it. The Leave campaign effectively ignored him. Had the country voted Remain, Farage's arguments to leave the EU would have been a voice in the wilderness.
The country voted Leave, and Farage and UKIP's job was done. Farage is now a radio presenter and whistling winds blow tumbleweed through deserted UKIP offices across the country.
However - if a second referendum was announced and the EU inevitably gave us a punitive deal on the back of it, "persuading" Brexit voters of a nervous disposition to return to the sect, then there would be outrage among all Brexit supporters. Nigel Farage would become the most popular politician in Britain and there would be massive surge of support for UKIP. Imho.
Because the referendum wase'll never know the true breakdown, but...
Some of the 52% voted for £350M/week to the NHS
Some of the 52% voted for control of our borders regarding EU citizens, making our own laws AND keeping access to the Single Market and Customs Union - and no-one who wanted their vote was telling them it couldn't be done - unlike now, as their votes are now in
Some of the 52% voted for a complete break and didn't care about the economic carnage that will result in the short/medium term
Some of the 52% voted to leave because they feared it would eventually result in the United States of Europe
Some of the 52% voted to Leave just to give the powers-that-be a bloody nose for failing them in areas the government has always had complete control over
Some of the 52% voted to Leave because they didn't want Turkey joining the EU (like the Daily Fail said it would) against the will of the UK, and didn't realise that any one country could veto it
Some of the 52% (my very nice elderly neighbours) voted to Leave because they didn't want more Asian immigrants coming to the UK
There are lots of reasons why the 52% voted leave. I've only suggested a few of them. Every vote was by an individual with their own specific reasons. They don't all match, and you cannot just add them all up and treat them all as the same when deciding the manner of our leaving. particularly as the government is now a minority government propped up by the DUP and riven by their own internal factions - something the referendum was actually intended to resolve (and Cameron got it wrong).
Continuing the discussion further to explore just how we might leave and how we can work with the EU once we have left is the democratic thing to do.
