Well, the thing is that traditionally American politics did not have parties that were consistently conservative and liberal. Both parties had STRONG wings that consisted of liberals and conservatives. It was not based on party. Barry Goldwater and other conservatives in the Republican Party strongly considered breaking from the GOP to form a new conservative party WITH conservative Democrats before he rose up the ranks of the GOP.

I agree Canada is much more on the center. When the Liberals and Progressive Conservatives were the two dominant parties, the PC Party frequently ran to the LEFT of the Liberals. Red Tories --- Joe Clark and their ilk. Canada was pretty similar to America in that regard as both the PC and Liberal parties had factions. And the same thing that happened in America is slowly occurring in Canada. Stephen Harper's Conservative Party is way further to the right compared to the old PC. The Liberals do remain factionalized.
