Some people argued that the NDP will suffer the same fate as the Lib-Demm in the last UK elections. In particular, because NDP supporters are less commited and more likely to switch their vote, they will end up performing under what the polls predicted. It was true most of the campaign.
However, look at this graph from the latest Ekos poll. The NDP voters are actually more likely to vote now, as compared with the Liberals. We find similar evidence in the latest Angus-Reid poll. So, another effect of the orange wave... And another reason to worry for the Liberals.
By the way, I'm busy making the final projections that should be up Sunday morning, and for sure Sunday evening.
