Polls are coming out daily for the upcoming US federal election. But I want to talk to you about a big problem with polling. After a person tells a pollster who they intend to vote for, it involves finding out how strong the person’s support for that particular candidate or party actually is. Many years ago, I worked for a political party in Canada. And of course we did a lot of polling. Now the political landscape is a bit different in Canada than the US. In Canada, we have three viable political parties, a conservative party (often goes by different names in different provinces), a Liberal Party and the NDP (extreme left).
