The difference between the Conservative vote in 2006 and the Conservative vote in 2008 is the increase in Liberal and New Democrat vote, a smattering of votes for the other candidates and a large group (almost 3,000) that apparently didn't vote.
These would be almost entirely Provincial Conservatives who were constrained in their choices by activities within their own normal political camp.
The New Democrats were primary beneficiary of the Feud with an increased vote of 5810. Some 2927 didn't vote, apparently. The Liberal vote share increased by 2635.
Overall turnout was slightly above that of 2004 - when there was another spat within the Conservative party - but the total count of eligible voters increased as well from 2004 to 2008.
Liberal and New Democratic vote share did not change appreciably from 2004 to 2006. The increase in Conservative vote in 2006, compared to 2004, can be attributed to a suppression that resulted from internal problems between the Provincial and federal Conservatives. In 2006, the Provincial Conservatives supported their federal brethren openly.
