During an election, there should be a central place to see
-My constituency (boundary data)
-My ward
-The authority running the election
-How I register to vote
-Who is standing for the election
-Where my polling station is

All of the data is available - but it's held across different departments, separate websites, in PDFs, and sometimes behind paywalls (Ordnance Survey).

I've built a demo using some of the available data at http://voteuk.shkspr.mobi/

I'd really like an authoritative API - to much is out of date or disparate.
