I realize that this is possible, since I used to be one myself before I moved rightward on issues other than monarchy. However, as I wrote two years ago, the left-royalist position (what I call "neomonarchism") is becoming less plausible since leftists are becoming more openly hostile to constitutional monarchy, especially in the English-speaking countries.
I have seen Canadian "conservatives" flock to a known Chomskyite statist politician and not to his principled conservative counterpart (political issues speaking) just because he happens to pepper his speeches with "God save the Queen!"
Really? Somehow I doubt that this is all that common. I just find it difficult to believe that today's Canadian leftist politicians are eager to prove their enthusiasm for the monarchy.
if you force me to choose a constitutional monarchical system with Her Majesty Queen Elizabeth II as head of state, Helen Clark or Jean Chretien as head of government, and a republic with George Washington as both head of state and government, I will choose Washington, thanks.
Helen Clark, as you probably know, is a republican who has announced that she thinks it is "inevitable" for New Zealand to break with the Crown, so no monarchist would want her in power either; I'm not sure what your point is. And the George Washington option is not currently available. In any case, as an unreconstructed Tory/Loyalist, between George Washington and King George III, I would have chosen the latter--without denying that the former was an honorable man, far superior to most of his successors.
Oh yes they do. Have a look at the Monarchist League of Canada's forum. ( http://members.boardhost.com/monarchist/ ) It is full of monarchists who would be classified as Howard Dean Democrats on everyday issues. There are even posts cheering Adrienne-Clarkson despite how wacky her background is and how bad her conducts in office have been just because she is the current Governor-General of Canada! I'm a conservative-by-issues person (but then, like Mark Steyn, I think it is best for the Queen to stay as HOS), and I can never agree with such people.
One thing to note in particular is the perspective of "brownie nationalists". Indigenous peoples in New Zealand and Canada have respectively stated their support of continuation of the monarchy because historically they had signed treaties with the Crown and they could use the link with the Crown to re-engineer New Zealand (or Canadian) into an "ideal state" where the indigenous peoples are more equal than the others. Sorry, but this is class-race-gender New Left ideology, and I can never justify my support of monarchy linked with this fad.
