You may or may not recall, and chances are that you won't, that I linked to a review of electoral management by UEA Senior Lecturer Toby S James a while back. It was concerned with changes that could be effected by centralising electoral management in order to improve processes for voters. If I'm not mistaken, the paper also points out that low confidence by staff manning the polling stations in the processes undermines voters' confidence in the polling process. Of course as such it's lovely to hear the the Conservative Party addresses this in their manifesto. There's just the slight difference in perspective, as they are eyeing the introduction of ID requirements for voters.
A few mornings ago, one particular episode of the FiveThirtyEight Politics podcast stuck with me, from April 19th (oh boy. A month ago). In the last segment they open to questions from the floor, with a noticeably British woman asking about the state of polling in the UK. I attended university under the tutelage of the UK's answer to Nate Silver and his FiveThirtyEight team, Chris Hanretty, and as such my interest in the answer to this question was picqued.
