That is not accurate. You are referring to the partisan political tribesmen. They do not want the Biden's investigated. I suspect most people are like myself, in that not really minding whether they are investigated and not particularly worried of results for better or worse, have the firm opinion, the Supremes are meant (by design) to be the arbiters of legal definition, there is nothing to indicate they are actually superior individuals, of unparalleled moral character and never has been. Throughout government, it has been shown to be necessary, that the people set rules for personal conduct of (particularly) management of the various departments of our government, with sanctions for misconduct or the permissive appearance of misconduct, not to be broken. That there should be standards for those at the top is without question.
As I said, I have no problem with the President being investigated and open to investigation. I only wish they were not as blatantly, publicly political partisan, in the way they carry out the necessary and designed in function of checks on ultimate power, the goal, not so much making sure the sitting president is not involved in an active nefarious scheme, but to find a political reason for simple embarrassment and political advantage. In this day and time, I suppose it is to be expected. They have been smelling smoke and foul stench from Hunter's ass for over 7 years, but unable to link Joe in a provable way, whether he is or not. The lack of provable link that would hold up in a court (our real standard) could be one of three things: (1) A true link does not exist and Hunter being a shit primarily on his own, though taking advantage of his father's name, as spoiled assholes often do. (2) The republicans are further demonstrating their usual standard of legal ineptitude. (3) The Bidens, like the Clinton could actually be that much smarter, simply, their attackers, while not actually inept, but still decidely overmatched by a very small crowd, this being the Supervillain theory, requiring Batman or some other Superhero to intercede on the part of the struggling mismatched partisans hoard. I doubt this one the most.
