From https://serverfault.com/election:

2011: 3,834 voters were eligible, 566 visited the election, and 310 voted (8% of eligible users voted)

2012: 6,350 voters were eligible, 1,361 visited the site during the election, 474 visited the election page, and 208 voted (3,2% of eligible users voted)

So - we have more users, and more people visiting the election page, but less votes - even with nearly twice the userbase. What's going on?
