It's not a model, it's an omen.
The main lesson from the Canadian experience is that the more socially conservative Reform/Canadian Alliance party there couldn’t make much inroads into more socially moderate Ontario or Quebec until it socially moderated a bit when it merged with what was left of the PC. The party’s leaders were often portrayed as scary theocons with a “hidden agenda”, even though there really wasn’t one. Social conservatives need the help of fiscal conservatives in order to win elections in Canada as much as fiscal conservatives need help from social conservatives. That's probably true south of the 49th parallel as well.
