How would Alaska behave as a Canadian province?

[Neo-Malthusian Misanthrope]

Good question. Far northern Manitoba and Saskatchewan tend to vote very strongly NDP, which is a similar pattern to what's observed in very rural and remote Alaska due to the indigenous population. I also thought that Peltola's coalition was broadly similar to what elected Notley premier of Alberta thanks to a split on the right between moderate and more extreme candidates but of course RCV means that isn't quite one-to-one. I think Alaska would end up voting between Alberta (thanks to resource extraction and general culture) and Manitoba (thanks to the urban/rural split and rural indigenous populations), which would work out to be mostly conservative but not overwhelmingly so, especially as cities like Anchorage grow, plus some shades of the territories (Yukon in particular). An extension of Northen BC might be another comparison but I'm not very familiar with the area.

Quickly eyeballing things provincially, the centre right party (maybe the PCs or maybe an Alaskan-specific party) would generally be favoured but the centre-left party (almost certainly the NDP with nary a Liberal in sight) would usually be a strong opposition with chances to break through like we might see in Saskatchewan this year. Alaska's trend of making bipartisan coalitions in the state house would probably lead to the creation of something like an "Alaska party" in this hypothetical version. Federally, they'd have at most 10 seats, which I see splitting about 7:3 Conservative to NDP with some wiggle room on either side. Perhaps a Liberal would have snuck through in Anchorage in 2015. As Ottermax said though, a Canadian Alaska would have developed differently from an American one, so who knows what novel trends might have emerged? Rural Canadian politics tends to be hyper-local, anyway.
