I think quite a few Labour MPs, many of those from leave constituencies will end up backing the deal. I think most the Tories will grudgingly or otherwise back it, apart from the hardcore leavers.
From a remain perspective, it seem like it might be ok. Seems we're still strongly aligned to the EU, crucially for things like employment and environmental regulations. We won't have a say in those laws, but then the UK is generally one of the countries pushing for business over people laws anyway. It's definitely worse than staying in the EU, that much is obvious, but its a case of stick or twist. A hell of a lot needs to happen for the UK to stay in the EU, a lot less needs to happen to leave with a worse or no deal at all.
