Actually it makes a sort of perverse sense as the Brexiters though that they were delivering damaging blows to Parliament, and reducing it's power over them.although brexit is supposed to deliver more control to parliament, the thing brexiters fear the most is parliament gains control of brexit. Mad.
For a large percentage they really thought little further than that, as they had been told the EU was the source of all evil, and then would you believe it, Parliament then said it wanted to stay in!
They felt it had betrayed them
Which was in fact true.
As to showing Parliament that the public rule.
How naive can they be to believe that?
