>There is already partisan support within those provinces, and Trump is going to offer money to push it. If that happens, Yukon and the Northwest Territories are next. (Side note: these are Republican voters, which gives Republicans the Senate for years to come.)

Disagree.

1. If any Canadian province becomes an American state (with electoral votes), the Republicans won't win an election for the next 100 years. Even if it's Alberta.

2. Alberta likely won't secede unless they get full statehood. Nobody wants to be another Puerto Rico.

3. I think if you did a referendum in Alberta today (even with full US statehood on offer), the votes to secede would number over 10%.

Remember, Quebec in 1995: 50.58% voted to stay, with a turnout of 93.52%. And they were all but ready to leave to the point of engaging in IRA-style terrorism.

Also, the famous failure of Brexit all but precludes any such referendums from getting serious wind in our lifetimes.
