How could that be so?
In 1812, the two major parties in this country were the the Republican Party, which would change its name to the Democratic Party in 1840, and the Federalist Party. The overriding issue in 1812 was the war that had recently broken out with Britain. "On to Canada!" was the slogan of the Republican Party while the Federalists ran on a "peace" platform.
I doubt if there is anyone, Democrat or Republican, in this country today who wants to take over Canada.
I do, I will trade them the North East corner of the USA and the West coast for the middle portion of Canada. Then the socialists in Quebec and the North East can freeze and starve while we get the oil sands in Alberta
Give it back to the Mohawk traditionalists ~ they want to bring back ceremonial cannibalism
