Heh, sorry.
First thing to understand is that while parliament is voting on what May should do next, most of the votes are non-binding. I think Cooper’s is the exception where it locks into law something that would allow MPs to require she request an extension to the Brexit deadline. Other than that, May can do whatever the hell she likes still.
It’s fairly clear now that she plans to go back to the EU and tell them that the deal is unworkable and she only stands a chance of saving it without the backstop - she’ll do this regardless of how they vote. However, she’s looking for as many MPs as possible to get behind that proposal because in theory it makes her argument to the EU that it’s a way through the deadlock look more plausible.
Either way, the EU will almost certainly just tell her to think again.
It sounds like we’re having another “meaningful” vote in mid-February on whatever May’s managed to fudge between now and then.
