Coalition governments of both the left and the right are quite common in countries, like most of Europe where there is proportional representation rather than first past the post. While not without drawbacks it would be a good reform in my opinion.

No idea, but he keeps winning because the left vote is split between 3 parties, while the right only has 1. He keeps winning by like 38%~ people voting for him. While the left parties get 59% of the votes. And considering only old people vote for him and they vote the most, he represents something like 20% of what the Canadian public wants..which is completely fucked.

Not lately. It's been like this since Harper. He took Obamas dick in his mouth and hasn't taken it out since he was elected.
