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.
