Why even the polls put out by NDP'ers show "strategic voting" makes NO sense for St Catharines

Many St Catharines NDP supporters are publicizing a poll/projection which claims a 7.6% lead for the NDP over the PC candidate in St Catharines, and both far ahead of the Liberal incumbent. This is so far over the margin of error of 3.9% that it makes no sense to vote "strategically" if you don't agree with the NDP as you'll be wasting your vote, they don't need it! To make your vote truly count vote for what you believe in. But don't just take my word for it, take a look at what St Catharines NDP supporters were saying about so-called "strategic voting" just 3 years ago! https://www.niagarafallsreview.ca/news-story/8183384--people-are-voting-for-what-they-don-t-want-/
