I think May's position was strengthened by the hardliner's failure to get 48 signatures. As one Tory MP said, "This is how Vote Leave would have looked without Dominic Cummings."
But now, the actions of the DUP today make her position weaker.
So, in this coalition of chaos, it's pretty much a game of snakes and ladders. More interesting to watch than play unless you're one of the many snakes.
