Thanks, enjoyed playing with the app. What about the estimated 2m+ Tory voters who stayed at home this time? What impact does small increase in turnout have eg tories less than 3% behind in 35 seats. Surely next time they will focus on a better get-out-the-vote operation in their 292 second places

You would have to think so. Ok my app it’s a little annoying to deal with non-voters - essentially it would mean add to the Cons and taking a small amount away from each other party for the case you mentioned.
