Alan, you seem to hold a higher regard for politicians than most people. Politicians follow the herd instincts, they don't want to rock the boat, they react only as the last resort, and frankly, most of them don't have the mental capacity to plan ahead.
I think politicians are morons and government is too big. But I don't want to turn over the country to scientists who aren't elected and report to no one. When they screw up, they just go back into their ivory towers protected by their tenure. Politicians do risk getting fired which sharpens their reactions.
As far as not rocking the boat, Trump actually is more likely to do that than most politicians because he isn't a career politician. His being a maverick is what got him elected. His success in business helped as well. He knows how to execute, something many politicians have no idea of. They've never ran anything. He has.
The reason his poll numbers are going up because people see how he operates every day at his news conferences. All the lies about how he does everything himself is shown to be BS. Beside the medical community, he brings in military, FEMA , and other key administrators to show how he leads them but allows them to get the job done. All the BS you;ve been reading for four years how he's this John Wayne character doing it by himself is nonsense. One man can;t run the American government. However, people now see he knows how to organize, direct, manage, and is intelligent in understand all the details of what going on. The press lied about that and now people are seeing first hand that he's a powerful and knowledgeable leader. That's why they all want him to stop the conferences. It makes Biden, who is hiding in his basement, look small by comparison.
