Its not cringey at all, its making the point Labour overwhelmingly voted to trigger. The realities are that anything else would have been seen as undemocratic and unfavourable. Even the Blairites are mostly on board with his approach because they recognise their constituencies demanded so.
I'd love to know what you think he/Stamer should have done. They've had nothing to argue against other than a mantra of Brexit means Brexit so all calls for single market access etc were hollow. They fought for a whitepaper and for a vote and thats what they got, now they can rally against the terms, this was never about Article 50 itself.
In terms of what choices he had during the week of the vote, he had two choices, both of them bad. However his lack of decent choices came as a result of months of poor leadership and worse communication.
The unhappiness around A50 comes from two issues and how they relate. The first thing to acknowledge is that triggering A50 gives a huge amount of power to Theresa May. With A50 being irreversible & time fixed it means that any deal she can come up with, we have to take, basically. There’s no meaningful vote at the end, unless a choice between Theresa May’s deal and crashing out on WTO terms can be considered meaningful. With no opportunity to change our minds during or at the end of the process, voting now for A50 is giving May the proverbial blank cheque. Likewise, if May says she needs secondary legislation in order to meet the terms of the trade deal, what choice does Labour have but to support it, even if they don't like it? Force the UK out of the EU with no trade deal at all? Expect Labour to be put on the rack again and again over the next two years.
The other issue is that Labour’s position since Brexit has been so muddled and confused that they’ve failed to become the champion of soft Brexit in the minds of Remainers. That’s partly an actual lack of a position, with leading figures all contradicting each other over the last few months. But its partly about poor communication, a continual achilles heel for Corbyn. This graph from YouGov's polls a couple of weeks ago says it all. The lack of clarity means that people who were unhappy with the Brexit vote see nothing they can relate to in Labour’s position. Worse, they then see Labour hand Theresa May the votes she needs to get A50 through easily, and feel betrayed, knowing the power it gives her.
However with the right wing media portraying any questioning of the Brexit process as antidemocratic, Labour have been extremely meek in how they've challenged the Government, for fear of being tarred with that brush.
What Labour should have done in my view is fairly straightforward. Take a clear soft Brexit position based around continued membership of the single market, in the sense that the EFTA countries are members, probably using Norway as a model that the public would understand. Make membership of the single market the red line. That would honour the referendum result, but also allow other things to happen.
Firstly, they would have appealed to those people who voted Remain, who also accept the outcome of the referendum but don’t want a hard Brexit. It would also appeal to those people who voted Leave but think that leaving the customs union and single market entirely would be bad for the economy. That’s a solid group of voters. Once May came out gunning for hard Brexit, that group would only have got bigger.
The other thing is that taking a clear Leave position would have nullified many of the moans of the right wing press. As I said, triggering A50 gives May a huge amount of power. Whichever way you voted, it suits almost no-one to give May such a blank cheque. Labour should have been exerting every possible pressure to stop A50 being triggered until we know an awful lot more than we do know, including being prepared to block it. They didn’t whip for A50 because they think the process is fair and robust, they whipped because they were worried about being considered anti-democratic, nothing more.
Once voting for A50 became a binary choice between giving May a free run at Brexit or denying the outcome of the referendum altogether, they had no good choices. But that situation could have been avoided.
