I really hate this because the uninformed and intentionally blind are making me look and sound like a Trump supporter and defender when I've detested him since the 80s.
You are completely missing the fact that Trump uses bankruptcy like we might use a crescent wrench. He has had several of his businesses declare bankruptcy on multiple occasions as a way to manage cash flow and capital assets. I hate it but that's a far cry from his business crumbling. I've never understood why banks gave him loans given his track record but I suppose he made it a priority to pay them back what he owed while he screwed his general contractors and suppliers.
I don't know if you're trying to be ironic or what. This sounds like something Don Lemon or Joe Scarborough would come up with.
A lot to unpack here but the evidence is that he did take the job seriously and that he targeted actions to get to things he thought were important -- fix the increasing leftward bias of the federal courts, take steps toward securing the borders, pull out of unending involvement overseas, making our allies pay their fair share for mutual defense, etc. It's fair to say you and others don't agree with his priorities but despite my personal animas against him, I'd have to say he took it seriously.
Winning the election when the Left has spent years on tactics to control information throughout the country and to manufacture votes when and where they want them is a whole other matter. He did turn a lot of people off by the way he pursued things but a lot of the repulsion was generated by the way his acts were reported rather than what he actually said or did. We've all seen how the mass media has twisted everything he's said and done. The Left thought they'd knock him out in 2016 but didn't realize how he was using Twitter to get around the mainstream media -- they did this past year or two and have been working to effectively counter him (and now, not only silence him but cancel anyone they can claim is associated with him).
Your last paragraph just makes no sense. If anything, Trump was the one in DC who was pushing to renegotiate trade agreements, pull out of being the world's policemen, etc. but you're saying he wasn't fit for the job. That is a complete and utter non-sequitur. Like the Left, you're conflating things like his encouragement for protesting the "irregularities" in the past election with the theft, vandalism, and deaths (even though those were far less in scope than the activities incurred this past summer from "peaceful protests" supported by the liberal elite).
