Hah, as an Edmontonian I'll agree that there are a hell of a lot of 'economic refugees' in Alberta. I can't walk to the store and buy a pack of cigarettes without running into at least three newfies...
I think we keep electing the tories because of lack of competition. We definitely don't want to go bankrupt with the NDP, and I think the liberals have just generally failed to get their act together. I personally don't like the tories and I'm debating if I really want to give them money so I can vote for the new leader - because whoever that is is likely to be premier for some time. I distrust any political party that has been in power for the last 40 years, and I can't help but feel that they are buddy-buddy with the oil companies. What I want out of my provincial leaders is an increase in the royalty rates, but no one has the balls to stand up to the Goliaths.
I disagree with the notion of the Alberta 'bible belt'. Yes, it is true that there are many socially conservative religious small communities, but they don't represent a large part of the popular opinion. Catholicism is big here, and I think we can all agree that the Vatican's tenets are a far cry from Southern US Evangelicals. I don't think religious concepts play a big part in Canadian politics at all.
As an Albertan who doesn't like the Conservatives, I still think that in the next election they might be the lesser of the evils. As Albertans, we historically have to respect Lougheed and Klein for standing up for Alberta. I criticize Ralph Klein for cutting social services and the whatnot, but he did do wonders for our economy. Hate 'em or love him, he's still King Ralph.
Even though I am fiscally conservative (and a proponent of Alberta's cessation, lpl), I think I'd like a more liberal government because I think that with our oil revenue, we are more able than other places to provide more extensive social services.
And if I can digress to federal politics... Alberta votes for the Conservatives because they are the least likely to screw us over. Even though it is before my time, the 1980 Federal Election where Pierre Trudeau won a majority without winning a seat east of Manitoba and went on the screw Alberta with the NEP is well ingrained in the collective unconscious.
