Just don't ask me to believe any Ultra Lobbyist cares about the country.
No one is asking you to accept that proposition. You have created a false dichotomy (lobbyist, or a person who cares about America) and are now using this false dichotomy as an excuse to shut off any critical thinking skills you have.
A lobbyist is a person who professionally advocates for a position on behalf of their employer. There is nothing about this which tells us that the person doesn't care about the country, doesn't believe in the issue they are advocating, and certainly nothing about this that says their opinion on the former president - based upon actual first hand experience - is not valid.
If you want to argue that their opinion should be disregarded you would need to go through them one by one and explain how their current position conflicts with their ability to give an honest assessment. That's how logic works.
The problem for you is that in order to show that their lobbying position is a valid reason to disregard their opinion you have to show the conflict, which means that the opposite position would go against their personal interests. In other words, if it turned out that Trump were good for their lobbying form then their negative opinion would be even stronger evidence for us to take into account. But what you're trying to do instead is dismiss their position altogether regardless of what they have to say. That defies reason, which is why you are (as so far argued) objectively wrong on your approach here.
Since you have a tendency to skim through and strawman what I said, please let me know if you need me to slow down and expand on any of that before responding with your usual throw away lines.
