Do you mean the midterms in 2018?
The economic data was softening and the Fed acted to avoid a recession. It's certainly not helpful to the appearance of the Federal Reserve's independence that Trump tried to bully them. But they acted within their mandate. Fairly bog standard response.
The main issue at the midterms was the assault on people with existing conditions. Since then, Trump has said one thing and done another: he says he wants to protect the vulnerable but he attacks the system which protects them in the courts.
I doubt the economic bounce back will be immediate, but we'll see. This isn't a situation folks have seen in the last hundred years. 15-20% unemployment is a tough backdrop for an incumbent.
