The options on the ballot paper were 'Remain' or 'Leave'.
The Remain campaign did a terrible job of promoting the positive reasons for remaining in the EU, preferring to engage in the negatives of leaving.
The Leave campaign did a very smooth job of blaming all of the UK's ills on the EU and at the same time promising all of the things that various demographics of Leavers asked for - control over immigration, more money for the NHS, sovereignty, continued free access to the benefits of the EU with none of the costs, etc.
The big problem now facing the Leave politicians is that they have to deliver on these promises.
The EU has not rolled over and agreed to any of the UK's demands. When Barnier diligently sticks to his brief, which is to look after the interests of the 27 EU members according to the instructions that the 27 sovereign parliaments have given him, he is accused of bullying, being obstructive and looking to punish the UK.
When Johnson promised that the heads of he German auto industry would demand that Merkel did a favourable deal, they instead told her that the integrity of the EU was politically and economically more important to them than the comparatively small market that is the UK [e.g. VW sells 4 million vehicles a year to China, and only 250,000 a year to the UK, from a total worldwide production of 10 million, so the UK accounts for less than 3%]
The rest of the world has not been knocking down the door to get a deal with the UK - the Japanese ambassador said that a deal with the EU was far more important and that the £80bn already invested in the UK would not continue if Japanese companies could not make a profit.
There is still no workable solution to the Irish border question.
Triggering Art 50 has already cost the UK far more than the proposed savings before the UK even leaves, when £20bn of increased costs on Customs infrastructure alone will make UK exports even less competitive and wipe out any of the supposed gains that Brexit would delver.
In order for the sovereign EU countries to discuss and ratify the final leaving agreement, there are fewer than 20 weeks remaining for the UK to come up with a proposal that satisfies the EU, the Leavers and the rest of the world. At the moment, both major parties in parliament are divided and arguing both amongst themselves and with each other about what this should look like.
I have no problem with the UK leaving the EU, provided that it is to the benefit of everyone in the UK - i.e. better welfare, wages, education, healthcare, prospects, housing, infrastructure etc. - but two years after the referendum, there is no evidence at all that this will be the case. Quite the contrary - the danger of a catastrophic 'No Deal' Brexit gets ever closer.
