I'm not convinced Trump wants a second term.
He seems to view trade balance as his legacy, and he doesn't appear to care anymore how it affects his popularity. Trump wants to be seen as the "guy who brought fairness to US trade deals with the rest of the world". Whether you agree with him or not about whether international trade had been fair to the US over the past decades is certainly up to the individual.
If that's how he wants to be known that's bad news for him because he's failed at it. He's gotten several minor concessions from our closest allies in exchange for demolishing our credibility for a generation. It's been a total disaster.
