You make a good point - but mainly it is a separate one to the main thrust of what I have put forward as the way I could/can see things unfolding.I'll not pick at the detail of that but it was going well till the last sentence. Two out of the last three GEs have brought no overall majority (and the other one didn't give May a big enough majority over her own bastards to be confident of getting a deal). So a GE may not bring anything to a close.
In other posts I have been clear that I am against a 2nd referendum as for me that just rewards the shenanigans the Remain dominated HoC as they will ensure that the questions are totally loaded - I would vote Remain before I would vote for May's deal and also there is a lot of Brexit fatigue.
I see a 2nd referendum as simply a way for the Remainers to legitimise abandoning Brexit by getting the electorate's fingerprints on the decision and saving their faces and the trouble of revoking.
For me if a GE has Brexit as a central factor I really think that there could be a workable majority.
If I was a Remainer - I would want a referendum
As I am a Leaver - I want a GE
