Individuals don't run the government, something that will become clear as day by the end of next quarter.
A single person couldn't possibly have the bandwidth to be able to direct government, especially someone over the age of 70.
Do you really think Trump or Biden are sitting down and drafting executive orders themselves? Do you even think they came up with their campaigns themselves?
There are organizations behind these things, composed of partisan ideologues. That is how you get the bullshit in the last administration and the bullshit in this administration.
