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.
And if that option wins, a pool of citizens who have marked that they’d be willing to serve a term in government get randomly selected from each riding to fill each seat. You can only serve if you haven’t ran federally before.
