re: Theresa May is the worst PM since Neville Chamberlain

That's the point. May's job is to ensure Brexit does NOT happen! This "soft Brexit" deal was designed to fail. The whole idea is to set up a false choice for the voters in the UK for either hard Brexit or Remain, where the establishment and media can browbeat the populace with histronics, shaming, and hyperbole so that they vote for Remain in a second referendum. That's the playbook.

Just like Alabama, when the establishment loses, they can give themselves a mulligan. When they win, they have a mandate.
