Surprises/Analysis this election (only two):
1. The collapse of the Bloc Quebecois, mostly at the expense of the NDP. Conversely, the holding up of the NDP vote in Quebec, which I expected to have been diluted a few percentage points from what the pollsters predicted. Even if the NDP and Bloc vote swung 3% (in opposite directions, so a net effect of 6%), it only would have impacted the result of 2 seats that the Bloc were trailing within 6% or less from the NDP (Montmorency–Charlevoix–Haute-Côte-Nord, Gaspésie–Îles-de-la-Madeleine) but for the rest of the seats the NDP victories were crushing. This was the biggest mistake that my prediction model made, by far.
2. Elizabeth May. She has absolutely proven me wrong when I incessantly harped about how that along as she is leader of the Green party that the party will never win an elected seat in the House of Commons. She won with 46% of the vote against Conservative Gary Lunn, who lost with 36% of the vote. I would be highly curious to know what happened with the local campaign there during the election. Although I disagree with mostly everything that comes out of May’s mouth, she has to be congratulated for her victory in Saanich–Gulf Islands.
