A very good one!
I've wondered how Conservatives have kept control of the Commons for so long, considering how bad their PMs have been (and how short their times in office have been). I thought Cameron was the best, and HE called the BREXIT referendum!
He called it, both thinking it wouldn't pass, and saying that it would be non-binding.
What he should have done is 'age-rated' it (younger votes count for more, older votes count for less), and said that it had to be more than a bare majority.
But the Tories are all still asses.
