Alberta & Saskatchewan would both vote Republican if they had long traditions of being in the U.S., but if they were cut out and annexed now, both would vote Democratic, if only to protect their healthcare systems. No one in Canada, not even conservatives, would trade their healthcare system for the American one, and "American-style healthcare" is often used as a scare term in Canada.
Isnt healthcare run though at the provincial level , I can bet if a deal was made to make them states they would get to keep that.
Their prescription drug prices would skyrocket.
