Ken, as I understand current legislation an early election cannot be held unless 2/3 of Parliament agree.
That is what happened in 2017.
Corbyn currently says he is in favour of a general election (notwithstanding the polls) but, if he chooses, Labour could vote against it .
If Johnson's request for an early election is refused, Parliament could then revoke s 50 or legislate for a second referendum.
Both these positions were only a few votes short in Parkliament before and could well pass if Corbyn took a stand instead of continuing the dithering that has so damaged Labour.
You have said many many times that this is not possible. Repeating it ad nausium doesn't make it so.
1) It can't be left-of-center to argue that the second referendum matters more THAN getting the Tories out.
And no one could seriously argue that it's a progressive outcome to stay in the EU and have the Tories stay in power.
In any case, it goes without saying that it's impossible to persuade any current Labour Leave MP to ever vote for a seconde referendum. If it was possible to do that, it would have happened by now.
Just as there is nothing Corbyn could have said or done to change a Leave victory to a Remain victory in the original referendum, just as there were never any magical words Corbyn or any of the people who stood against him for the leadership in '15 or '16, none of whom ever had any personal popularity whatsoever, that would have prevented what happened them, there is nothing he can say now to any Labour Leave MP to switch any of their votes.
It's simply not worth trying since there aren't any Labour Leave MPs who aren't locked into an absolute Leave position. Even a three-line whip would make no difference.
And, since EU policy forbids socialism-and since nothing less than full-blooded socialism can make any difference in the areas that matter-there's nothing Labour could offer those voters in the North and Northeast of England who voted Leave that would make any difference in their lives, that could address the decades of economic neglect of that part of the UK by previous Tory and Blairite governments, in exchange for getting them to switch to supporting Remain after all. You can never get economic revival of the North and Northeast under market economics and on an austerity budget, both of which the EU makes compulsory.
Nothing good comes of any scenario where a second referendum did happen but the Tories remained in power while it happened. All any delay in the calling of an election can ever do is increase the chances of the nightmarish prospect of a Tory victory.
There's nothing in the EU that is worth that-and you don't have to obsess on staying in the EU to oppose xenophobia.
It might be different if any of the Remain obsessives were proposing any serious campaign to change the EU, and that campaign had a chance of victory-but they aren't because they know changing the EU isn't possible, and because the Blairite component of the People's Vote movement don't want the EU to change-they actually want it to stay just as it is, and they want any European government elected on an anti-austerity platform anywhere to be subjected to the humiliating subjugation imposed on SYRIZA.
And, let's be honest, that's what you want to. You never accepted that Corbyn's victories in 2015 and 2016 were landslide votes to repudiate the Third Way. You tipped your hand when you all-but-salivated at the prospect of Tom Watson-a man who still defends the Iraq War-somehow becoming leader.
