I notice though, Naomi, that -- rather like in the Clinton/Trump election, when I piled into Trump as hard as I possibly could but struggled to find much positive to say about Clinton -- you seem somewhat unable to sell the Tories positively. It seems that the best reason to vote for them is that they can't possibly be as bad as Labour. Well, even if that's true, it's a very low standard to set, and as Clinton supporters found out it's not a very convincing case either. It doesn't work, as I found out already, so I'm somewhat surprised that you are trying it yourself.
So what is the positive case for voting for the Conservative Party on their own merits? For myself, I can't support May's vision of Brexit, I can't support her decision to expand grammar schools and religious schools so aggressively; I can't support her apparent lack of interest in Climate Policy; I can't support her determination to reach an arbitrary and damaging target for net migration. So it's in my interests to try and combat that as best I can. That means voting for Labour (or the Lib Dems if they had a hope of even winning more than 10 seats). For other people, there is a positive case to vote for the Tories, plain as day, because no position I hold above is the only position one can reasonably hold.
It should go the other way too. At the very least, you should accept that Tory policies can be -- and have been -- equally damaging, and that if one wants to hold the governing party to account for that then... well, then I guess there is no alternative but a Labour government.
And yes -- yes that does suck. Why is each election essentially a binary choice between two equally unappealing options? (something something first past the post sucks)
