1) Any Alberta government elected in 2015 would have had trouble being re-elected in 2019. As was the case in Venezuela, the slump in oil prices made hard times inevitable and no government could have done anything there to make itself popular enough to win this year. The same question hurled at the Chavista government , "why didn't they diversify the economy?", could be asked of the Alberta NDP, as it could have been asked of every government in Alberta and Venezuela that governed before the PSUV and the Alberta NDP
2)Governments presiding over a continuing recession at election time are almost always defeated, wherever they come to power.
3)It was always going to be futile for the Alberta NDP to try to out-pipeline the Right. Nobody can out-pipeline that crowd. It was pointless, as well, for Notley to go to war with every non-Alberta wing of her party over the Leap-nobody who hates the idea of the Leap was ever going to start voting for her party. The only hope she had for any chance of re-election was to focus on turning non-voters into voters by carrying out policies that actually inspired enthusiasm from those alienated from politics. It isn't possible to win over voters who traditionally vote for the right by appeasing their conservatism-the only way to connect with those voters is to have a strong, coherent set of ideas for the future and to speak out for those ideas with conviction and without apology. That approach CAN win over some traditional right-of-center voters, because it comes across as leadership.
4)The Alberta NDP has a strong base to build from, but it can only build on it by reaching out to those its leader spurned and directly addressing the fact that Alberta cannot remain an "all that matters is the oil" province much longer. At some point in the next few decades, the oil will run out. The voters will be looking for a party that commits truth on that and that conveys hope for a future grounded in diversification away from extractive industries and the building of a sustainable economy for the post-oil days to come.
