If Wexit occurs, is admitting AB + SK for PR + DC a politically viable deal?

[Del Tachi]

To be honest, you are delusional if you think Alberta and Saskatchewan would vote R if in the US.

You don't think provinces which vote 70% Conservative might vote ~55% R? I guess you'd take the deal then, right?

30% Liberal creates a Democratic floor of that much. Democrats then need to win about 30% of the Conservative vote. I think this is a very easy task for Democrats to do considering differences in the 2 nations political systems, as most Canadian Conservatives are in an ideological range similar to Charlie Baker and Heidi Heitkamp, and still very much to the left of Larry Hogan and Joe Manchin, let alone comparisons to Ted Cruz and Donald Trump.

Stephen Harper would disagree . He was more conservative than Mitt Romney was and many Republicans are and not only did he dominate Alberta he was the PM of Canada for almost 10 years

Yeah, the liberalness of Canadian politics is way overstated.  This isn't Sweden or France.  Harper and other Reform-style Conservatives mesh very well with Republican ideology, and that's especially the case in SK + AB (not as much in ON or QC, but that's not in question here)
