On the second point it should be noted that the awful FPTP system creates the regional distortions that make it appear that the regions are more divided than they really are. One looks on the map and it seems like Alberta is near uniform blue but that's because of FPTP. The reality is that ~64% voted one way and a sizeable amount of Alberta voted in opposition.

If we fixed our voting system to be more truly representative I think some of these divisions would go away.
