How do you figure? The guy was 4 - 5 years in the US. If anything, he is more British, as he was there for 30 years.
Also, personality wise, I find Harper and Iggy to be very close to each other - both are controlling, type A personalities with a bit of megalomania tossed in for good measure. Harper once mused on how he wanted Canada to be more like America, and that the Republican party was a "beacon of light to the rest of the world" or some such nonsense.
The main difference I see between the men is that Iggy is more respectful and dignified in the way he acts and cares himself, where as Harper is an embarrassment every time he opens his mouth with his hyper partisan, rude and obnoxious behaviour. Iggy has also shown a lot more respect for the Canadian parliamentary system than Harper has while he has been in power. If anything Iggy is much more "Prime Ministerial" than Harper just for his demeanor.
In any event, I want policies, a vision and future for this country, beyond Harper's copying everything the Americans do, and blaming the Liberals for everything that goes wrong.
