With less than two months to go till the May 14 British Columbia provincial election, we can expect to see a wave of opinion polls. The most recent poll from a major public pollster suggests the NDP has a 19-point lead over the ruling Liberals.
As you can see, pre-election results have been bouncing up and down since the beginning of the year – something that tends to happen with pre-election polls. (Click graph to enlarge.)

Note: The sampling error margins given here are those provided by the pollster. While online polls have had a high level of success at predicting recent elections, there is a methodological controversy surrounding the citing of margins of error for online polls. Some experts hold that it is inappropriate to quote a margin of error for an online poll because participants in such polls are drawn from volunteer panels, rather than chosen at random from the general population.
