Yeah, most Canadians (except some in the interior) are bat-crazy liberal. Would be nice to have a highway to Alaska, but not at the cost of importing more crazy. Not fond of anything "Indian" to be honest, they want too many privileges.
There is a certain level of socialism ingrained in the current Canadian system. Especially in regards health care and pogie (unemployment). I'm not so sure that would flange up well with our system.
In addition, though, the VAT (GST plus value added taxes at the provincial level) are brutal (15%) in the east, not so severe in the interior provinces (just the 5% GST). What I think would be beneficial is a good, resource extraction based partner, an independent country.
I think a lot of that would get sorted out, and there would be a better chance to make additional states after a period of that, provided the former Canadians wanted to do so.
When you talk about the interior, though, From Manitoba to the interior part of B.C. is similar in many ways to their counterparts on the US side of the border. Eastern Washington State and Eastern Oregon are different from the coastal parts, not just population density wise, but in general philosophy, much like Northern and Eastern California.
Idaho, Montana, and North Dakota, are all States which have relied heavily economically on resource extraction, be it coal, metals, or oil, and on agriculture as well.
Birds of a feather.
Yes, urban areas seem to be more Leftist/socialist/"liberal", increasingly with population density, but we are talking about low population density areas which only have concentrations of people related primarily to their industries. IOW, they tend to be more conservative in their thinking, especially compared to the largest cities on the coasts and even in the continental interior which indirectly mine the resources of the more rural areas, while focusing on the problems in their urban back yards to the detriment of the very areas that provide the resources they demand.
From Alaska to Texas, there is a vast strip where the thinking is similar, the ethos is something people have more in common than with the majority of their urban neighbors on the coasts.
Statehood might prove to be too great a jump, but I'd like to see them independent of Ottawa.
