I'd like to think that the Tories are more Southern representative while Liberals are more representative of New England but it is hard to say because we're dealing with different countries. Determining which party would be abolitionist and which party would be secessionist essentially determines which politicians would fall where.
Saying that Liberals would be the party of racism, the Confederacy and the like just turns them into the Democrats and makes for a boring exercise.
I'm going to say the Liberal and Conservatives bases are the same as the republican and democratic except that Jews vote con instead of the liberals.
Jews don't vote Liberal as reliably as they once used to, but it was just twelve years ago that the Liberal candidate received over 90% of the vote in Mount Royal.
