A few major changes:

[selectricity] / app / controllers / site_controller.rb

class SiteController < ApplicationController
  layout 'vb'
  model :user, :election

  def index
    if session[:user]
      session[:user] = User.find(session[:user].id)
      @current_elections = session[:user].elections.sort do |a,b|
        b.enddate <=> a.enddate
      end
    end
  end
end
