There are approximately 2.8 million eligible voters in Alberta and the UCP received 927,000 votes which is 33% of eligible voters and 52.6% of votes actually cast. The NDP received 776,000 votes which is 28% of eligible voters (16% less than the UCP) and 44% of votes actually cast. On a pure percentage of the vote basis, 52.6% would result in 46 seats and 44% would result in 38 (with the other 3.4% given to "others" in the form of 3 seats) which is not that far off the actual results of 49 UCP and 38 NDP.
At a 61% overall turnout, it's also not a "pretty bad turnout". It's nowhere near Singapore's typical mid-90% but it's quite a bit better than Luxembourg. It's on a par with Canada nationally and with US presidential elections

It's harder to find comparable provincial or state statistics than national ones.
The interesting thing for me is whether the NDP can continue to consolidate "the centre" and not embrace the far left the way the UCP has embraced the far right. I thought they ran a reasonably competent campaign with one exception - they had a strong economic platform (even with their nominal hike to business taxes) and I don't think they were nearly strong enough in presenting it. It was as if they simply ceded that ground to the UCP (ground that the UCP certainly didn't earn or deserve) rather than aggressively present their own plan...
