One Democracy Club (DC) plan for 2016 is to create candidate lists for all 2016 UK elections (much like we did for the 2015 general election (GE2015) with https://yournextmp.com). Last night @ Citizen Beta (Cß), Mark Longair rightly flagged that this is quite (very) ambitious! I realised I have no handle on just how ambitious i.e. how many candidates we’re talking.
The Electoral Commission have a list of upcoming elections: http://www.electoralcommission.org.uk/find-information-by-subject/elections-and-referendums/upcoming-elections-and-referendums
Below are the numbers I’ve found so far for each.
