Mark Steyn is keeping his American colleagues up to speed on what's happening here in the wilds of Canuckistan. He cites an interesting example from Australia back in 1975 where the Aussie PM considered having the Queen fire the GG before the GG could fire him. The PM was too late - the GG got to the Queen first.
I doubt that Harper is seriously contemplating anything along those lines - the people and media would go ballistic. Nevertheless, Steyn's concerns about the potential for lasting damage to the Canadian system seem real.
