If you don’t think it relates to the question at hand, why did you brought up the point in the first place?
I think you are too much focused on Trump (likely because the media likes to focus on Trump) and not on how a successful campaign to repeal the act would look like. It’s unlikely that Trump makes it his agenda, but that’s not required given that the legislature is independent from the executive.
Congress does have leadership that’s separate from the president. People like Nancy Pelosi have political power.
You also have a lot of other organizations. Organizations like the Chamber of Commerce can drive legislative change as well.
