The argument from a stunningly successful Leave campaign that "it was our money anyway" clearly worked.
This story is full of huge political miscalculations, most notably at Downing Street.
But the biggest in Wales must be the decision by Welsh Labour to leave it so late to start campaigning to remain in.
By the time they did get out onto the streets of the south Wales valleys, and cities like Newport and Swansea, it was too late.
The narrative of a crisis in immigration had been set and it was like trying to turn round an oil tanker.
There are all sorts of strands but this was about class and money more than anything.
Leave campaigners told us repeatedly the Vale of Glamorgan and Monmouthshire were the most Euro sceptic in Wales, and yet they, and Cardiff, voted to remain.
These are the parts of Wales that regularly top league tables for affluence.
The so-called "left-behind" communities across Wales had their say.
As one pundit said this morning, it was the "masses" against the "classes".
And so this morning, huge questions about the role of a Labour party that has traditionally represented them.

The body of 39-year-old Anayat Bibi was discovered with multiple stab wounds at a house in Vickers Road, in Firth Park, at the weekend.
A 42-year-old man from Sheffield is expected to appear before magistrates on Friday.
Police said two other men, aged 83 and 20, arrested in connection with the killing remained on police bail.
Ms Bibi's body was found by police at about 11:35 BST on Sunday.

Members of the Public and Commercial Services Union will walk out on 19 May.
In a ballot, 96% of the 150 affected members voted for strikes on a 53% turnout. 247 people are employed at the office in St Paul's Place.
BIS said it will provide "comprehensive support" to affected staff.
The government announced plans to shut the office by 2018 in January.
Mark Serwotka, general secretary of the Public and Commercial Services Union, said: "This vote sends the clearest possible message to BIS ministers and senior officials that these plans are wrong and must be reversed.
"The closure of this office is precisely the opposite of what the government claims to want for the North and the wider civil service."
He said the union was also considering a timetable for further walkouts.
Announcing the plans, permanent secretary Martin Donnelly said it was part of a move to create a combined central HQ and policy centre in London and establish six business centres across the UK.
He said the decision was taken in an effort to "modernise the way we work, reduce operating costs and deliver a simpler, smaller department that is more flexible and responsive".
A BIS spokesperson said: "Whenever a proposal such as this is made, people's livelihoods and families are directly affected, and these decisions are never easy. It remains our top priority that all our staff are fully briefed and consulted during the process.
"We take their future and the contribution they have made very seriously, and will provide comprehensive support to all those facing a potential change or loss of job."

Rail electrification is already going ahead in south Wales but no decision has yet been made on the north.
The Wales Office and Welsh government are working with businesses to make the case for the investment needed for the project to get the go-ahead.
But Mr Osborne said a decision would be affected by the HS2 project and a rail hub possibly being created in Crewe.
Electrification means faster and more reliable services which help businesses and their workers who commute.
Welsh Secretary Stephen Crabb also said electrification could be a game-changer and could happen in the longer-term.
Speaking on a visit to Denbighshire, Mr Osborne said: "Lets make the decision first on HS2 because that new rail hub at Crewe will be crucial for north Wales and it's crucial for the investments we're making in the north Wales economy."
This is an extraordinary rejection of the EU in Wales, especially in the areas which have received the most EU cash - the south Wales valleys.
