Yes, it freaks me out too. Progressives have been tracking Trump’s failures with the expectation that the bottom is about to drop out and then it will all be over. What they don’t understand is that as long as it’s him and not Obama, Hillary, or some other elite that’s in the White House, he can do (or not do) whatever he pleases.
Trump might not have killed Obamacare and replaced it with something more generous, built a wall, or brought back a single factory job, he might have kept NAFTA and the Iran agreement intact, but that just makes his most ardent supporters long for him all the more. Ted Nugent and Sarah Palin don’t do anything for Trump voters either, but, like Trump, they affirm their anger and estrangement and reflect it back at them.
The election may be over, but this is still a culture war, and it’s still a campaign. The less Trump does for his base, the angrier they will be at the progressive elites that they blame for their troubles (and his troubles too, because they believe that he’s one of them).
For now, that’s all that matters.
