Revised list of the12 ridings with the slimmest margins of victory which gave Steve his majority.
My original list from May 5, 2011 is back here, with corrected details and more data.
The Sixth Estate's list of alleged electoral fraud is now up to
50 68 77, 100 ridings, 6 of which appear here on the list of closest vote margins.
Update : As per David P Ball of the Vancouver Observer in comments below : his list of the top 11-closest Conservative wins where robo-call fraud is alleged, along with a little background on each of those ridings.
"The top 11 "robo-call" ridings amount to a 14,813 vote margin - almost exactly 0.01 per cent of voters.".
