Re: "2). Calls an election in the hope that it will distract attention from #1"
So, it's acceptable for May to change her mind about an election? I agree. I think "u-turn" is one of the most toxic terms in politics. We should welcome politicians who are prepared to change their minds and respond to evolving circumstances.
But then, I'm afraid, I can't see how you can object to Sturgeon saying the very different circumstances that now prevail mean that the previous "once-in-a-generation" promise also has to be revisited.
Or are only politicians you like allowed to change their minds?
