In some ways, I think Harper is just a continuation of Brian Mulroney. He sucks up the the USA by putting American interests before Canadian interests (Harper did it in a military way in Afghanistan, while Mulroney completely Canada out to Reagan and Bush senior with FTA in 1989 and NAFTA in 1992), both try desperately to appease Quebec nationalists, and both were corrupt in their own little ways (the only difference was that Harper already has scandals going into his 3rd year while Mulroney managed to last much longer).
Between the two, I would even say that Mulroney was in some ways better. He was open minded towards Native issues, while Harper just shums the issue completely, and Mulroney helped set up employment and assistance funds for new immigrants while Harper rejects them because they're not white.
Nonetheless, the similarities are clear. Harper is another Mulroney in the making, both had weak and useless Liberal leaders to oppose them.
