NDP have definitely closed the gap, particularly in Calgary. Unfortunately, they have created 'fear-mongering' (i.e the UCP is going to change healthcare for the worse; the UCP are bad for minorities etc etc); and distraction away from the more important issues facing this province.
I predict a UCP minority which would not be a bad thing.
Yeah. It has been super interesting. Here are the available regional breaks from recent polls. Given the expanded margins of error of the smaller sample sizes, most of these are in the margin of error. Important to note, for Angus Ried and Ipsos, Calgary is the CMA, this map:
Pollara provided these maps of their split:
If you think about it, and integrate the results in your head, you can see that Calgary proper is probably tighter than the headline numbers suggest. Pollara's split between the city and region shows that the voting patterns are not the same. Angus Ried and Ipsos have them close while including a good chunk of not Calgary. The informed guess that results for me is that Calgary is entirely in toss up territory.
The polls:
Also interesting: if you dive into the polls, women are much more likely to be undecided, and half of those undecided women say they would never support the UCP. So if they show up at the polls all of the polling is basically shot - Calgary goes orange, and we could end up in an unstable minority government, unless the Alberta Party can win 3 seats. Otherwise, it could be a thin majority for either side, though I have trouble counting ridings to get the NDP above 42 seats.
In the last what I would call province wide votes (humour me here), the PC leadership race in 2011 (since you could walk up and vote by buy a membership on the spot, and every riding had in person voting stations), the 2012 provincial election, and the 2015 provincial election, women turning out at decisively higher numbers (what a former colleague called spontaneous self organization) tilted the races big time. It happened before, and can happen again.
