Users enter their postcode and then we use the api at www.mysociety.org to look up their local Clinical Commissioning Group. Armed with this information and the data that the NHS Support Federation pulled together we can tell the user about what their local services need and what they're likely to get from each political party.
Because of the short notice we had to pull the site together in record time - but hey, that's just the kind of challenge we like.

(unless the election is all over in which case you're probably too late...)
