I think you're confused about what municipal, provincial and federal governments should be advocating for their constituents. I'm from BC which is 4th by GDP and I believe we crack the top 3 in Income tax paid. For that the only recollection of federal involvement lately was them criticizing our infrastructure spending(buying ferries from China) and how we'll get to take on most of the risk from a pipeline with little of the reward and even less input.
This isn't a criticism of Charlie or even what he's doing, it's completely fair he wants to do things on his own accord. It's about the general ideology that exists on what needs to be done to truly make changes.
To put it another way many Liberal supporters(I'm not one) want Pierre to stay on like some hardcore Conservatives do. Pierre staying is bad for Canada but good for the Liberals, in the same light Conservatives would love for all progressives to operate outside of the actual political system. It just pushes Canada towards the American system where real progressive politics exist almost entirely outside of the system with influence.
Even without Venezuela Trump has been very clear about wanting to drop oil prices. Whether it be lobbying OPEC, global trade instability or whatever "drill baby drill" is suppose to be.
For the latter part of your comment. I'll point to Trump's approval ratings, while as whole it's dropped noticeably his MAGA base is still pretty positive on him after pretty shit year for Americans. Alberta has a base where they'll point to Trudeau even though he'll be years removed and they saw peak outputs/revenue during his time.
