Why not? He needs a job, has name recognition and is uniquely Canadian. While some might argue his annoying character would work against him, I would suggest a quick review of our last few Prime Ministers- annoying seems a prerequisite. He has massive charisma and a disarming sex appeal that would project well. The Canadian Tire guy has shown a natural propensity for problem solving and quick decision making, which are essential in today's political environment. He is a tireless(no pun intended) community servant, always willing to lend a hand to a person in need.
Just imagine Stephen Harper in debate with the Canadian Tire Guy. Harper wouldn't stand a chance against this industrious thinker, quick with rebuttal and alternative viewpoints. So, with that in mind, I think a draft the Canadian Tire guy grassroots effort should be initiated. Canadian television's loss, may well be federalism's gain. Think about it.
