Ibbitson says such fawning nonsense about Sheer, whose nonstop grinning is because he doesn't know what to say or do, and doesn't have a good grasp of his surroundings. As speaker of the house, Sheer was a pushover with no initiative, who simply gave free pass to Conservatives' shenanigans, smiling all the while because he didn't have the backbone or understanding to do different. That's why he was made speaker: Because he wouldn't provide resistance and everything would just pass by him.
We'll see how it goes, but I suspect that, whatever people think of Trudeau and the Liberals, making Sheer leader of the Conservatives is like putting a kid who plays T-ball in the major leagues.
