They don't want to do that, those would both add solidly democratic senators, and likely permanently cost them the Senate.
Not like Canada and Greenland, which are notoriously conservative and would vote for Republicans consistently. Ignore the comparatively liberal policies, those aren't related. Quebec and Greenland in particular are just chomping at the bit to jump on Republican mainstays like adopting English as the one true and official language of the US.
They don't want to do any of this. They want to propose ridiculous pipedreams that they cannot hope to accomplish, and wouldn't enjoy if they did, because it distracts from their lack of ideas or morals.
Every conversation about Canada and Greenland is one you're not having about sex crimes and class warfare.
I think you attribute far more cleverness to them than they have. I don't think they care if we're concerned about their lack of morals or ideas. Why would they? All the information needed to know about that was publicly available before the election and it didn't matter. The people who would care already know, and the people who wouldn't... There's no reason to distract them. Not that it matters, since they won and we can't exactly change that.
I can assure you my snark here doesn't reduce the amount of other conversations I'm having elsewhere. I can hold opinions on multiple topics at once. ;)
I wouldn't put it past them to actually want this insanity. People said the same things about how talk of overturning Roe was just a distraction because it's a "settled matter" and doing it would be insanity.
Imagine if they're not actually playing 5 dimensional chess. Imagine if their platform is exactly what they say it is, and their dumb ideas are real. If they respond to claims they don't have any ideas by saying they have the best ideas, and to claims of immorality by calling them lies and calling the accuser a pedophile.
I think people want them to be more clever than they are, because it means that people got duped, rather than their surface level idiocy being super appealing to a lot of people.
Alberta may be conservative by Canadian standards, but I think they'll end up as a collection of blue states if you did that. America is quite far to the right ward on average.
