Obviously with another election that means the referendum loses that much moral authority, it's no longer the most recent vote.
Uh . . . well, she was _in favor_ of "the referendum" right? So why would she be interested in doing something that would reduce the moral authority of that referendum?
Honestly, your system baffles the shit out of me: oh hey! lets have another election, why not!?
She does not seem to be stupid, and I'd bet she is not doing this without collaboration by other Tories, eh? So, they must think it is a strategically wise move, despite the fact that no one (other than Vladimir Rasputinivich Putin) can determine the outcome of an election . . . There is of course the risk that the conservative party loses control in such an election right?
On the other hand, what do you gain inherently or stochastically from an election?
I would presume that there is _some_ degree of inherent gain in 'strength' or favor among the non-elite, non-establishment, non-left aspects of U.K. citizenry, simply from CALLING an election. It demonstrates bravery and confidence and is also likely to motivate those who feel strongly about the issues to engage with voting.
This sort of inherent benefit, might well be subtracted to some extent if opposition is able to leverage their position effectively. Given that opposition is "the left" and much of the mass media and intelligentsia in Britain swing left, I'd say there is no trivial risk of opposition being able to gain some traction from an election. Granted, their ability to do so might be limited by the fact it is a short time frame and this may well have taken them very much by surprise but . . . in sum: this seems like it may be a rather double-edged sword?
And then of course, the vagaries of election.
Despite our common middle-to-right leanings on this board, I think it behooves us to acknowledge that, in our societies (US, UK, France, etc.) at this time, populations seem to be roughly half-and-half divided between leftists and rightsts. The margins by which Trump won were not particularly large and I was under the impression it was the same for recent conservative wins in the UK. A win by Le Pen would similarly be fairly narrow I presume?
Lots of factors come into play in an election and the obvious risk would seem to be that the Torys not only do not extend their majority but suffer a setback and lose that majority?
Given the Brexit thing is more-or-less final, I find it strange to take that risk at this time. But then maybe Brexit is not so "final" as we have been led to think? With an inscrutable bureacracy like the EU, there may well be fine print somewhere which was overlooked until recently and which change the strategic forces in such a way that: going forward toward finalizing the Article 50 actions, the conservatives have realized they NEED a larger majority in Parliament?
