Every single reason she's given for calling this election is bogus. The opposition parties can't scupper her because she has an overall majority, and the Lords can't scupper her. Brexit is supposedly signed and sealed way before there's an election "looming." This is all about trying to fix her own right-wing, nothing else. A weak party leader in hock to her own hawks. Puppet masters if you like. She'll need a big majority of mostly complicit softies to overcome them. She may not get it, and she hasn't got the charisma to face them down.
