The writer's premise is that not only is Andrew Scheer wrong but 31% of the Canadian population that voted for them are also wrong.  Wrong, by definition, means not agreeing with the writer's opinion.  My guess is that more than 31% of the people agree with Scheer's comments on Khadr.  And Trudeau and the Liberal party knows that and that is why the announcement came just after Justin left the country and the ten million dollar payment was made so quickly.  The Liberals biggest fear is that number of people is very large whether the writer likes that or not.
