The outcome is happening right now, and it's following the Remain predictions fairly closely.
Freedom of movement gone, massive cost increases for exporters and importers, staff shortages, food shortages, the NI problem, etc.
Cummings confirmed what was already known: that the Leave campaign lied. He hasn't yet confirmed that the whole thing was manufactured by tax evaders. There has always been anti-EU sentiment, much of it respectable and well argued. It was only when the tax and money laundering directives came out that the campaign started. The rational leavers were replaced by charismatic racists, Russian traitors, and accelerationist crazies. The currency traders made a fortune crashing sterling (one spent 32million on Leave advertising, and made 800).
Well, we're all adults, and we have to live our choices. Unfortunately, we also got the full house of the most corrupt and incompetent government in modern history, the pandemic, the open looting of public money and a spineless press.
