Never invade Russia in the winter. Never fight a land war in Asia. Never go for a third term as Prime Minister in Canada. It makes the electorate hate you. I don’t complain much about his policies, but Trudeau is screwing his own party over and now we might end up with the Trumpiest of Canadian politicians as PM.
Sure, and there is a reasonable discussion to be had about how pollsters compose panels and use statistical techniques to try, with varying degrees of success, to make those panels more representative of the population. However, simply dismissing all polls as “voter manipulation” is unreasonable.
