Actually it's a well-known fact here in Canada that Alberta was populated by (among others) a large number of Americans who drifted up from the plains, from as far south as Texas, bringing their guns (and sometimes little else) with them -- except their attitudes. This makes Alberta the hotbed of anti-gun-control sentiment, for example. And it has a lively and thriving separatist feeling.
It even started a new party, Social Credit, based on a weird fimancial model: if money circulates, real wealth is generated. So they issued an Alberta 'dollar' which depreciated at the eand of each month, so people played 'hot potato' with these dollars, then turned in what they couldn't get rid of at the end of each month, for
fewer next-month's-dollars.
This policy didn't last long, for some reason.
The party was anti-eastern-canadian, anti-big-bank, and anti-Semitic. (You know, the "international Jewish bankers' conspiracy"). This was potent stuff during the Depression years.
William Aberhart, a prominent evangelist in Alberta, (founder of the Prophetic Bible Institute), founded the Social Credit party there and was premier from 1935 until he died in 1943. Ernie Manning, Social Credit, was premier of Alberta for about 25 years. He also hosted 'Back to the Bible Hour' on radio.
(British Columbia also had a Social Credit party in power for many years, under Premier W.A.C. ("Wacky") Bennet.

The Social Credit party followers in Alberta voted (old) Conservative federally, where Social Credit was nowhere (nationally). The Conservative party gradually morphed into the Reform Party, after the traditional Conservative party died in 1993. The Reform was populist, though, and there we see the influence of Alberta. The Canadian Alliance party (containing Stephen Harper) was formed when people from these different groups realized that no individual one of them would ever form a national government. So they formed a single party renamed "The Conservative Party of Canada", which did quite decently inthe 2004 election. And of course Harper won this year.
He had to key down his pitch to do it, though. And the only reason he got in was because Canadians had finally become disgusted by the arrogance of the Liberals. Of course, if Harper had decided to go for Premier of Alberta instead of Prime Minister of Canada, he could have been much more up-front about his
real agenda -- and won.
Still, Alberta supports socialized medicine. If you let them have access to private services as well.
