A newer more likeable puppet would not change the course of history because it is the ideas that are wrong (deliberately so, it seems) and not the person reading (or trying to) the teleprompter.
The triangulation has begun where the “left” is going to blame the personality and NOT the policies for failure.
True, they are going to try to make it about Joe Biden. The good news is that all of their contenders are flawed (at best). The Right is going to have to play the blame game this time, because this is not a normal political environment. We are seeing our society come apart at the seems.
