No Trump hasn't done shit,, good one.. that's why a web site was started to keep track of all his accomplishments. There were hundreds of quality changes he made within the first 6 months. None of which you are aware because fake news CNN left it out, they would rather talk to Story Daniels lawyer
Every president since the invention of the web has had a similar website. I remember Obama had one, and Bush before him. I don't think Trump is as awful as your average American does - he hasn't screwed up nearly as hard as Bush the II did - unless you mean going by his personality, in that case he's about the worst president America has ever had.
The presidency is just a figurehead position. It's basically meaningless. If you don't think 99.9% of a president's decisions are controlled by his cabinet, his advisors, and military/corporate interests, you're living in a dream world.
