Here's the problem you extreme Brexiteers have though - and it's a problem you had from the start. It's that you have no viable alternative. You never have. So all May has to do is say "what's your alternative?" and you have nothing to say.
All you ever had was crashing out on WTO, which wasn't viable. Because you couldn't present one rational argument as to why Brexit was a good thing for the country, you can't counter something that is obviously a bad thing for the country.
Therein lies the irony - the Brexiteers themselves have made EU membership look better than anything else on the table. Because it always was better. All you ever had was soundbytes and misinformation. By lying about this being the 'easiest trade deal in history', 'taking back control', 'we can separate free movement from free trade' and 'we have the upperhand because of German cars' and all the other nonsense, you played a key role in this nonsense we have before us now.
Your best chance recently was supporting a second referendum on the terms, with 'No Deal' on the table, so that the country as a whole could take collective responsibility on doing something that suicidal if they wanted to. Instead, you feared scrutiny, barking from the sidelines like yapping dogs and being easy to ignore due to inherent extremism and no substance.
But it isn't just the Brexiteers at fault. The other side haven't once accepted that we could leave if the proper process was followed - instead, they wanted to frustrate Brexit altogether, pretending to be on the side of democracy when they were every bit as self-serving as the Brexiteers are; politically gambling on the opposite outcome because they were smart enough to know a 'hard Brexit' would never happen, because whilst 52% voted for Brexit, 0% voted for comparative economic ruin.
This isn't really May's fault. She had literally no choice but to do what she's done - her job is to lead a government and get this through parliament, how's she meant to do that with two diametrically opposed camps with nothing in the middle?
The fault lies with cabinet jobsworths voting to save their own skin tonight, and political extremists refusing to compromise and see a middle road, so May has had to fudge one herself. May has made only one really fatal error in my view - she should have resigned after the GE, as she no longer had the political capital to lead on this issue. She gambled and lost, and should have walked. The Tories didn't push her - they should have.
I said it in 2016 and it's true now - the non-binary referendum should have been what it was - advisory - and the representatives we send to parliament to act on our behalf should have been able to do their job and act in the best interests of their constituents, cross party, without a predetermined view of what Brexit means. If we had done that, we'd have had a semblance of a negotiating position and we could have got something less favourable than membership of the EU but not the total nonsense we now have in front of us.
But we didn't do it. C'est la vie.
