The Election page here says:

139,718 voters were eligible, 87,022 visited the site during the election, 33,846 visited the election page, and 6,573 voted

However, both the result calculation pages (OpaVote and the one by Michael Mrozek) both list 6,574 valid votes.

Where's the extra vote coming from?

May be that ghost voter is Community ♦. –  hims056 Mar 13 '13 at 4:11

Maybe someone voted with two accounts and they were merged immediately afterwards? –  toscho Mar 13 '13 at 4:23
    
@toscho That seems most likely (or a user was outright deleted), as only 6,573 users are listed as having been awarded the Constituent badge for this election. –  Tim Stone Mar 13 '13 at 4:28
    
It's all coming true –  Rory Mar 13 '13 at 9:34

up vote 5 down vote accepted

Well, inspecting the ballot file, there are 6574 lines of votes (besides, MichaelMrozek's page is just a formatted version of the raw OpenSTV output -- since the format/algorithm is by OpenSTV, I'd trust their data more). I doubt that any are invalid -- the election system tries to prevent that. This probably is a bug on SE's side.

However, there are 56 votes where a user has neglected to vote for their first (and/or second) choice, and have directly given their second/third choice. Going through them, it seems that they are all OK, considering that this counts as a valid vote (the preferences get shifted).


Toscho makes a good point. The number of voters in an SE election is probably counted directly from the vote input (which is later converted to the BLT1 file). A user merge/deletion may be the root of this.

A whole file full of BLT goodness? Makes me hungry, too! –  Andrew Barber Mar 13 '13 at 5:09

There probably should be a system in place to negate the vote once the user account is merged, since it shouldn't have been cast in the first place. OTOH, I doubt this is a problem on a wide enough scale to merit that much attention. –  Asad Mar 13 '13 at 5:12
    
@Asad: Yeah. This was a problem in a certain election (can't give details), but again, it wasn't such a large problem that the sockpuppetry influenced the outcome. –  Manishearth Mar 13 '13 at 7:29
