I think there has been a serious misinterpretation of what the OP was addressing, but I am not particularly surprised. I may not have been entirely clear, either.
I don't think Trump has some magic wand (although I do believe he thinks he does) and can dictate (although he clearly would like to) which counties can and can't open up, but... He desperately wants to influence the process directly. Why counties? That doesn't make any epidemiological sense, or geographic sense, or resource sense... but it does make political sense. Who do you think came up with this idea? I/You know it wasn't the CDC, or the Surgeon General, or anyone with a lick of sense. There are a number of sycophantic Governors out there (De Santis, Reeves) who will follow whatever Trump proposes, even if it goes against the interests of their own State. There are even more local authorities who will do so. It's called a bully pulpit for a reason.
Moreover, there isn't anything conspiratorial about it. The administration has already taken numerous official actions to directly punish "blue" jurisdictions. It's not some kind of secret. This is just a continuation of that. As I said initially, "That is his vision: identify the blue counties, and keep them shut down, and allow red counties to open up business." He sees that as punishment because the only thing he cares about or thinks about is how to make money and who "likes" him. He couldn't give a **** about the welfare of people who won't vote for him anyway.
