My take on the situation ...
Ignoring the exact details of any deal, the key is - for the time being - it's the only game in town. Unless or until the cabinet reject it.
That being the case, the next step is to get the EUs sign off. Not quite a rubber stamping exercise, but Barnier has been keeping all parties up to speed so there's unlikely to be any killer flaws.
At that point, the House of Commons gets a look-in. They get the deal/no-deal choice.
At the moment - much as they may hate it - the ERG/JRMs are in a bind. They have no power in cabinet (unless/until someone resigns). They can stamp their little feet (or get the nannies to do it for them) but their only weapon for now is (allegedly) the Tory self-destruct button of a leadership challenge. While they really are that stupid, they have to talk to some grown-ups first about that, so it's not as easy as it might have seemed a few weeks ago.
Those Leavers on this thread who have said they want a No Deal crash out (with all that a No Deal implies e.g. food/medicine having to be stockpiled), how are you feeling about a deal now possibly happening? Would you press for this deal to be rejected?
I think the answer there is that it's not winner stays on. You get one shot, and one shot only. (Yes, there is a subtext ...). You voted leave. This is leave. You don't like it ? Well there isn't another one for you. And if you aren't happy with the result, maybe you should have had something in writing to work to, rather that setting light to Farage Farts everytime anybody wanted to know what "Leave" looked like.
Life's too short, but I'm pretty certain that whenever Leavers wrote on these threads what they would be getting from Brexit .... this is not it. Nor will it ever be.
My personal feeling is that May has upped the ante ... if Leavers don't like this there's only one option: a second referendum.
Bearing in mind, Theresa May wasn't expected to last till July 2017, to have got this far, and survived 2 party conferences .... well loathsome as she and her politics are, there's a reason we have the phrase "grudging respect".
I think the window of opportunity for any ERG mischief closed a while back. They are more than welcome to rubbish this deal. They can even vote against it. But that's the only choice they have now.
I really can't see there being any appetite (or airtime) in seeing JRM or Farage on every Question Time banging on about how we need to leave the EU in future.
