It could change because again Alberta(& the west in general) isn't as divided from the east as it used to be.
I personally do vote in every election from municipal to federal, I believe voting is more than just casting a vote for your team but also representing your demographic. If only parents voted it doesn't matter if the politicians were conservative or socialist, they're going to try and work for that demographic.
I think we need electoral reform, the problem is every debate I see on the matter we can't seem to agree on what kind. I think we need STV.
